"We request that individuals with specific knowledge of these issues from both the FBI and Justice Department brief Committee Members and staff," they wrote in the letter. 
They added that they also want copies of the transcript of Flynn's "intercepted calls and the FBI report summarizing the intercepted calls referenced in the media." 
The senators are asking that the briefing occur after lawmakers return from the week-long Presidents' Day recess. 
They added that their request for a closed-door meeting stems from reports that DOJ and the FBI were involved in the lead-up to Flynn's resignation. The DOJ reportedly warned the White House that Flynn may be vulnerable to blackmail by Russia.
"These reports raise substantial questions about the content and context of Mr. Flynn’s discussions with Russian officials, the conclusions reached by the Justice Department and the actions it took in response, as well as possible leaks of classified information by current and former government employees," Grassley and Feinstein wrote. 
Top GOP senators said this week that they also expect the Intelligence Committee to fold Flynn's resignation into its ongoing investigation of Russia's meddling in the U.S. election.
