The US Justice Department isn’t reopening a criminal investigation into former Federal Reserve Chair Jerome Powell for cost overruns related to the central bank’s building renovation project. Attorney General Todd Blanche didn’t rule out continuing to look into the project’s oversight and potentially take action if evidence of wrongdoing came to light. Blanche commented on a report released this week by the Fed’s Office of Inspector General that found no evidence of criminal wrongdoing by Powell connected to the $2.4 billion project. The report identified a series of missteps that led to surging costs for the renovation, which had been initially budgeted at $1.3 billion in 2020.

Also this weekend, President Donald Trump said he appointed Jay Clayton, his director of national intelligence, to help lead a White House task force on artificial intelligence as the fast-moving technology raises concerns about its safety risks. Clayton was the most prominent name cited by Trump in a social post announcing the creation of the group, which he said will coordinate the US government’s engagement on AI, including with consumers and the companies building it.
