This is the latest from our new stimulus blog.

And he and the president will issue regulations on spending no-nos. “A little hint,” Biden told a meeting of state officials yesterday. “No swimming pools in this money; a few other things.”

The meeting brought state budget officers and auditors to the White House to talk about accountability for the stimulus. The theme: Don’t waste it.

Th Energy Department released money for states to help residents weatherize their homes, lower their heating bills and invest in alternative energy. And the Transportation Department announced $12 million for two Pittsburgh-area airports.

Meanwhile, House Speaker Nancy Pelosi continued to bat down flames over the idea of a second stimulus while some Republican governors continued to reject the first one. Texas Gov. Rick Perry officially said no thanks to $555 million to expand unemployment benefits. And the South Carolina legislature moved to overrule its governor, who vowed to turn down nearly a quarter of his state’s stimulus share.
