As U.S. Attorney General William Barr faced Senate Democrats on Wednesday, defending his rollout of Special Counsel Robert Mueller III’s report on the Russia investigation, a separate storm brewed in a House hearing room half a mile away.

It was just the move the Justice Department warned would deter Barr from appearing. Hours after his Senate testimony, Barr announced he wouldn’t be showing up Thursday.
