FBI Director Wray questioned

(CBS) -- Lawmakers questioning the new FBI Director wanted to know what he thought about a recent tweet from President Trump.

"Will you respond to this tweet, is the FBI's reputation in tatters?" asked Representative Jerrold Nadler (D-NY).

"There is no shortage of opinions out there," FBI Director Christopher Wray replied. "What I can tell you is the FBI I see is tens of thousands of agents and staff working their tails off to keep Americans safe."

President Trump picked Wray to be the FBI Director after firing James Comey. Wray’s been on the job since August, and Republicans grilled him about their concerns with recent and ongoing investigations.

“At the very least, the FBI's reputation as an impartial, non-political agency has been called into question,” said Representative Bob Goodlatte (R-VA).

Top agent Peter Strzok was recently removed from Special Counsel Robert Mueller's investigation after sending anti-Trump text messages to another FBI employee. Strzok also worked on the Hillary Clinton email investigation and has now been re-assigned to the agency’s human-resources department.

“There has got to be something more here it cannot be just some text messages”

Republicans say the actions of this agent call into question the integrity of Mueller's ongoing investigation and the decision not to prosecute Hillary Clinton.

"The inspector general is looking at a very important question whether or not improper political decision factored into the decision making,” said Representative Jim Jordan (R-OH).

Wray also testified he had not seen any effort from the White House to interfere in Mueller's investigation into Russian election meddling and possible collusion between President Trump’s associates and Moscow.
