In 2018, accountants for the National Rifle Association began cataloging for its board of directors questionable financial arrangements that had led to millions of dollars in payments to a group of top executives and consultants. The NRA was experiencing cash flow problems, and the accountants were trying to address what they believed to be serious financial mismanagement.

For a year and a half, the NRA has employed an outside counsel, William A. Brewer III, who represents the organization in high-profile legal disputes and is also deeply involved in internal decision-making. The accountants believed the financial dealings they had found could jeopardize the organization’s nonprofit standing with regulators. Yet, according to a former senior official in the NRA’s treasurer’s office, Brewer tried to thwart their efforts to draw attention to the problematic payments.

The former senior employee, Emily Cummins, who worked for 12 years in the NRA’s treasurer’s office, quietly resigned in November as the group’s internal strife escalated. Cummins, in a written statement that began circulating this month among NRA leaders, including at least one board member, alleges that Brewer obstructed the work of NRA accountants and vastly exacerbated the organization’s financial woes as he charged it hefty legal fees. Cummins confirmed that she had produced the statement, which was obtained by ProPublica, but declined to provide any additional comments. Brewer’s firm said its work was justified and of the highest quality.

The statement lays out a list of allegations regarding Brewer’s legal work and his treatment of NRA staff as questions surfaced about his law firm’s billings, which totaled $24 million over a 13-month period. In the first quarter of 2019, Brewer’s firm charged over $97,000 per day, according to internal NRA documents posted anonymously online.

Cummins accuses Brewer of trying to intimidate, deceive and silence NRA staff who were processing his bills while some accountants were growing increasingly troubled by the organization’s mismanagement, exorbitant spending and questionable deals involving conflicts of interest. Former Brewer colleagues as well as written correspondence obtained by ProPublica broadly supported her claims.

Cummins wrote in her statement that Brewer “intimidated NRA staff and threatened our professional livelihoods.” She alleged that he used pressure tactics with staffers “to keep them acquiescent,” compiling what she called “burn books” filled with personal information that he could use against individuals.

“I witnessed what appeared to be unrealistic and duplicative billing from Bill Brewer,” Cummins wrote. “I witnessed that Bill Brewer himself created a 2018 cash flow crunch by interfering with accounts payable to prioritize paying himself immediately versus other NRA vendors that had been providing goods or services for months without payment, also jeopardizing the NRA’s biweekly staff payroll.”

In a lengthy response to Cummins’ account, the Brewer law firm and the NRA defended Brewer’s work and called his legal fees standard. The Brewer firm pointed to an NRA email it said Cummins wrote in August 2018 praising the firm. “They are good lawyers and seem to be good people as well,” it said.

Svetlana M. Eisenberg, a Brewer partner, told ProPublica that “the notion that our research team compiles opposition research, or ‘burn books,’ regarding clients or their employees is simply not true.”

Craig Spray, the NRA’s chief financial officer, said the NRA is “current on all its vendor payments.”

Brewer has been a central behind-the-scenes force in the internal struggle that broke out between the NRA’s top executive Wayne LaPierre and ousted president Oliver North. LaPierre has entrusted the future of his organization to Brewer, and in a statement this week said the organization has “full confidence in Bill Brewer and his law firm.”

As the gun group has fractured, Brewer’s firm has been a key player in a series of expensive lawsuits against former business partners, government officials and North, in certain cases seeking damages worth tens of millions of dollars.

For the last three decades, the NRA has been one of the most influential special interest groups in the country. Without an infusion of cash, and a return to relative stability, it could find itself on the sidelines of the 2020 election, a dramatic difference from 2016. That year, campaign finance records show the organization spent over $30 million to help elect Donald Trump, more than any other special interest group.

Internal NRA documents previously obtained by The Trace and The New Yorker described expenses and questionable transactions and business arrangements involving top executives, favored vendors and consultants. Through Brewer, the NRA said it had “serious concerns about the accuracy” of the reporting but would not comment on “privileged communications or personnel matters.” Attorneys general in New York and Washington, D.C., have opened inquiries into whether the NRA violated its charitable status by providing excessive financial benefits to its executives and supporters. The D.C. attorney general’s office declined to comment on its inquiry beyond an initial statement, and the New York office did not respond to requests for comment.

This month, four NRA board members publicly called for an “independent review of the millions of dollars in payments to Brewer, Attorneys & Counselors for legal fees.” But other NRA senior officials continue to defend the group. Carolyn Meadows, the NRA’s president, told ProPublica, “I have never worked with an outside law firm that is more on call, attentive and positively in tune to the needs of their client.” Charles Cotton, the NRA’s first vice president and chairman of the audit committee, added that Cummins’ allegations “reflect a misinformed view of the Brewer firm, its billings, and its advocacy for the NRA.”

Brewer’s NRA legal strategy suffered a setback in May, in a First Amendment case against a New York state financial regulator. A judge ruled that the NRA could collect no damages from defendants in their official capacities, even if it prevailed.

Brewer’s firm has offices in Dallas and New York, and has represented celebrities like 50 Cent and major corporations such as 3M, which ultimately settled an environmental suit for $850 million in 2018. Starting in the mid-’80s, he gained a reputation for pioneering unusually aggressive legal tactics, which could yield successful outcomes for corporate clients.

But the tactics caused others to question the firm’s conduct. In 1998, the Dallas Observer ran a lengthy story on Brewer, describing his firm, then called Bickel & Brewer, as “a pariah within the local legal community, accused of pushing the ethical envelope, running up the costs of litigation, and destroying the gentility of the Dallas Bar.” Brewer, a native New Yorker, characterized his firm’s approach to litigation at the time as “zealous advocacy,” marketing his practice to potential clients as “New York-quality.”

“Bill’s representation of the NRA is a classic example of ‘servicing the client to death,’” Hal Marshall, a former Bickel & Brewer partner, told ProPublica. “We tried to leave no stone unturned in our cases, and it often yielded great results. On the other hand the bills were hefty.”

In 2016, Brewer was fined over $133,000 for attempting to influence potential jurors and witnesses in a Texas case. He denied any impropriety and has appealed the ruling, raising the total to $177,000, which the Texas Supreme Court will hear arguments on soon. In 2018, a judge found that Brewer had failed to disclose the Texas fine in an NRA suit against an insurance broker in Virginia. After the omission was reported by The Trace, a judge threw Brewer off the case.

In addition to Cummins’ statement, ProPublica obtained text messages and email composed by former Brewer employees in March 2018 that alleged unethical behavior by the firm. Four former Brewer colleagues — three of whom were abruptly fired over the last two years — described a pattern of disregard for ethical billing and conduct. The texts and email were sent just before the NRA began to heavily invest its dwindling resources in litigation by the firm.

Early in March, an attorney who had worked as a Brewer associate sent an email to another New York City-based law firm. The firm worked for a hedge fund that was locked in a legal fight against Eco-Bat, a lead production company represented by Brewer’s firm. “A number of attorneys have recently left Brewer, concerned about the firm’s ethics violations,” it said.

It went on to say that a Brewer attorney believed he had been fired “for refusal to violate ethical rules.” The attorney thought he had identified a disqualifiable conflict of interest involving an attorney on his team, the email said. When the Brewer lawyer “confirmed his initial analysis,” the email said, “he was told to drop the matter and terminated the following Monday.”

Sarah Rogers, a partner at the Brewer firm, dismissed the emails and told ProPublica, “We cannot discuss this matter, except to note that the former associate’s claims are false and have already been rejected by an arbitrator.” Eco-Bat’s chairman and CEO, Howard M. Meyers, praised Brewer’s work and said that the litigation was “a stunning, multibillion-dollar achievement.” He added: “I’ve been Bill’s friend and client for decades. I have never witnessed, nor would I expect, anything less than the highest ethical standards from Bill and his firm.”

Travis Carter, a spokesman for the Brewer firm, told ProPublica, “All time charged to client matters is scrutinized internally for accuracy, transparency and value.”

Later that spring, Brewer brought a lawsuit on behalf of the NRA against New York Gov. Andrew Cuomo, the New York Department of Financial Services and the regulator’s then top official, Maria Vullo. The New York officials had released statements advising those doing business with the NRA in New York to assess the potential reputational risks of maintaining ties to the gun group. The suit accused the New York officials of engaging in a thinly veiled conspiracy to destroy the organization, costing it “tens of millions of dollars in damages.”

LaPierre touted the lawsuit in a speech at the 2019 Conservative Political Action Conference. “In real time right before your very eyes, we, the National Rifle Association, on behalf of all Americans, are fighting perhaps the most important piece of First Amendment constitutional advocacy in the history of our country,” he said.

The lawsuit, which was seeking to recover the money the NRA had supposedly lost as a result of the New York officials’ actions, became the centerpiece of an urgent fundraising campaign. On an NRA webpage soliciting donations, the text said, “Please give as generously as you can — and help win this life-or-death legal battle for the survival of the NRA and freedom.”

Over the last four months, the Brewer firm has also been involved in legal actions against once-sacred NRA allies. The NRA recently sued Ackerman McQueen, its public relations firm for more than three decades. Ackerman shaped the NRA’s image, and, through productions like NRATV, placed it at the vanguard of the culture wars. Ackerman has historically been the NRA’s most costly vendor — in 2017, the firm was paid more than $40 million. In a lawsuit in Virginia state court, the gun group accused Ackerman of engaging in deceptive billing practices, and leaking damaging documents that show LaPierre using the firm’s funds for lavish travel and custom suits.

Another Brewer suit, filed in New York, is against Oliver North, who spent a tumultuous year serving as the NRA’s president until he was pushed out in April, at the organization’s annual convention. During the meeting, a leadership struggle unfolded between North and LaPierre, who alleged that North threatened to release damaging information in order to extort him into resigning. In its suit, the NRA claims that the former president engaged in a “failed coup attempt,” absolving it of having to cover North’s legal fees in connection with NRA-related litigation. The suit also, in an unrelated aside, accuses Chris Cox, the NRA’s longtime top lobbyist, of taking part in the alleged scheme to overthrow LaPierre. Cox, who was beloved by many NRA staff and viewed as the natural successor to LaPierre, resigned in June. Before North stepped down, he was seeking to audit Brewer’s billings.

Ackerman, North and Cox have steadfastly denied the NRA’s allegations. In May, Ackerman filed a defamation suit against the organization, asking for $50 million in damages. That same month, the judge in the New York case, Thomas J. McAvoy, dismissed the organization’s recovery claims; it would get no damages from Cuomo or Vullo in their official capacities or the DFS. The NRA is still pursuing its First Amendment claims.

During the summer of 2018, Cummins and her fellow accountants took care to document their work. A variety of NRA vendors, including Ackerman McQueen, were receiving what some accountants considered unjustified payments, and an array of NRA officials and contractors had been involved in what the accountants saw as expense abuses and questionable deals not initially approved by the board’s audit committee.

According to Cummins’ statement, Brewer misled the NRA’s board and “used information gathered by NRA staff to fit different purposes and to frame a different story to the board of directors.” It also says that Brewer “effectively silenced NRA staff who uncovered issues needing board of directors attention,” and “influenced members of the board” by “selectively withholding information relevant to their decision making.”

Rogers, the Brewer partner, dismissed Cummins’ statement and said it “may reflect a radical misunderstanding of certain work my firm performed.” Cotton, the NRA’s first vice president, said, “I am not aware of any concerns that would preclude the firm from representing the NRA, period.”

Cummins concluded her statement by saying that, while still an NRA employee, she tried to sound an alarm regarding the NRA’s legal representation, writing, “I raised concerns about Bill Brewer internally and with the board audit committee.” According to Cummins, she was ignored.
