Rod Rosenstein, the top Justice Department official at the center of the firestorm over the firing Tuesday of FBI Director James Comey, will provide a briefing to the entire Senate after requests from Capitol Hill.

“Deputy Attorney General Rosenstein’s office has confirmed to Senator Schumer’s office that Mr. Rosenstein will come to brief the full Senate next week. The time and date are still being worked out,” said a spokesman for Democratic Senate Minority Leader Chuck Schumer.

Mr. Rosenstein will be asked about the circumstances of Mr. Comey’s dismissal. Mr. Rosenstein wrote a memo that the White House initially claimed was the basis for Mr. Comey’s removal. President Donald Trump later said he had decided previously to fire Mr. Comey.
