Former FBI Director James Comey said neither President Trump nor any administration official asked him to stop the Russia investigation.

“Did [the president] at any time ask you to stop the FBI investigation into Russian involvement?” Senate Intelligence Committee Chairman Richard Burr (R-NC) asked Comey Thursday during a Senate Intelligence Committee hearing.

“Not to my understanding, no,” Comey said.

Burr asked Comey whether Trump’s comments expressing hope that he would let former National Security Adviser Michael Flynn go was about obstructing justice or helping him save face.

Comey replied, “I took it as a very disturbing thing.”
