Deputy Attorney General Rod J. Rosenstein will brief senators Thursday afternoon on the firing of James B. Comey as FBI director, the office of Senate Majority Leader Mitch McConnell (R-Ky.) announced Monday.

Rosenstein accepted the invitation last week, but a date and time was still up in the air. The briefing, which will be open to all senators, will take place at 2:30 p.m. Thursday. Senate aides said last week that it is expected to be a wide-ranging discussion in which lawmakers will have the chance to ask questions.

Plans for the briefing come as Democrats and some Republicans have been raising questions and concerns about President Trump’s decision to fire Comey. Trump and his aides have provided shifting explanations for Comey’s dismissal.

After a McConnell spokesman announced the briefing, Minority Leader Charles E. Schumer (D-N.Y.) said in a statement that he hoped senators in both parties would “use this opportunity to seek the full truth” about Comey’s firing and to press for a special prosecutor to probe potential ties between Trump associates and Russia as well as any Russian meddling in the election — a topic Comey had been looking into.
