Days before he was fired, James B. Comey, the former F.B.I. director, asked the Justice Department for a significant increase in resources for the bureau’s investigation into Russia’s interference in the presidential election, according to three congressional officials who were briefed on his request.
Mr. Comey asked for the resources last week from Rod J. Rosenstein, the deputy attorney general, who also wrote the Justice Department’s memo that was used to justify the firing of Mr. Comey this week, the officials said.
Mr. Comey then briefed members of Congress on the meeting in recent days, telling them about his meeting with Mr. Rosenstein, who is the most senior law enforcement official supervising the Russia investigation. Attorney General Jeff Sessions recused himself because of his close ties to the Trump campaign and his undisclosed meetings with the Russian ambassador.
The timing of Mr. Comey’s request is not clear-cut evidence that his firing was related to the Russia investigation. But it is certain to fuel bipartisan criticism that President Trump appeared to be meddling in an investigation that had the potential to damage his presidency.
