Attorney general nominee William Barr said Tuesday in front of the Senate Judiciary Committee that he believes Special Counsel Robert Mueller is not purposely targeting President Trump and his administration, despite what the president has claimed.

Background: Barr, who drafted a memo last year criticizing Mueller's investigation, said he is going to make as much information from the special counsel public as possible.

On protecting the Mueller probe: "The scope of the special counsel's investigation is set by his charter and by the regulations, and I will ensure that those are maintained," Barr said.

Barr said he thought former Attorney General Jeff Sessions was right to recuse himself from overseeing the Mueller investigation.

Barr said he wouldn't recuse himself from a DOJ investigation if he disagreed with ethics officials' recommendation that he recuse.

On Trump and Mueller: "If a president attempts to intervene in a [Justice Department] matter that he has a stake in to protect himself, that should first be looked at as a breach of his constitutional duties."

Asked whether he would fire Mueller if Trump asked him to, Barr said: "Assuming there was no good cause ... I would not carry out that instruction."

if Trump asked him to, Barr said: "Assuming there was no good cause ... I would not carry out that instruction." "President Trump has sought no assurances, promises or commitments from me of any kind, either express or implied, and I have not given him any, other than that I would run the department with professionalism and integrity."

On the 2016 election: "I believe the Russians interfered or attempted to interfere with the election, and I think we have to get to the bottom of it."

On reporters going to jail: Asked whether DOJ would ever jail reporters for doing their job, Barr said: "I can conceive of situations where, as a last resort, where a news organization [knows] they're putting out stuff that will hurt the country...there could be a situation where someone could be held in contempt."

On immigration: Barr said he thought a wall would address concerns about drugs coming into the U.S., but conceded after being pressed that he knew most drugs come through official ports of entry.
