Grassley's committee has sought to interview two FBI officials from Justice

(CNN) The Justice Department has agreed to let the Senate judiciary committee interview two senior FBI officials who could provide firsthand accounts about the circumstances around the firing of former FBI Director James Comey, potentially resolving a weeks-long standoff that led senators to threaten issuing subpoenas, according to sources familiar with the matter Friday.

The department had initially raised concerns that potential Senate judiciary interviews of FBI officials Carl Ghattas and James Rybicki could have interfered with special counsel Bob Mueller's investigation, which is looking into the Comey firing as well as potential Russia collusion with President Donald Trump's associates in the elections.

But Senate judiciary chairman Chuck Grassley and the committee's top Democrat, California Sen. Dianne Feinstein, had demanded that the two men sit down for separate transcribed interviews to assist with their panel's investigation into possible administration interference with the FBI.

Final details are still being hammered out, the sources said, particularly the timing of the interview. Plus, the committee wants to the FBI to produce more documents before the interviews take place, according to the sources.
