ProPublica announced on Monday that contributor William Turton has joined its staff as a national reporter covering the FBI and the Department of Justice.

“William is a dogged reporter whose work for ProPublica has already unmasked the inner workings of the U.S. government,” senior editor Ronnie Greene said. “We’re enthused he’s joining us full-time as we continue to elevate our Washington coverage.”

Turton is an investigative reporter with more than a decade of experience focused on federal law enforcement, technology and national security. He has previously worked at Wired, Bloomberg News and Vice.

In his time contributing to ProPublica, Turton has reported on the Department of Government Efficiency and an unprecedented data-sharing arrangement between the Department of Homeland Security and the IRS. He also broke the news that FBI Director Kash Patel waived the polygraph requirement for top aides.

At Wired, Turton reported on Charlie Kirk’s plans to discredit the Rev. Martin Luther King Jr. and the Civil Rights Act, and he revealed that a shadowy company was registering thousands of businesses across America using fake personas. At Bloomberg, he focused on cybersecurity, exposing how flaws in virtually every major tech company were exploited to obtain information used in extortion schemes involving minors. He also reported from the U.S. Capitol on Jan. 6, 2021.

“I’m excited to continue my reporting on the Federal Bureau of Investigation and Department of Justice as these important institutions are undergoing an unprecedented transformation,” Turton said.
