"On my watch, Bob will be allowed to complete his work," Barr intends to say to Congress at the start of his Senate hearing Tuesday, according to prepared testimony released on Monday.
"I believe it is in the best interest of everyone -- the President, Congress, and, most importantly, the American people -- that this matter be resolved by allowing the special counsel to complete his work," he will say. "The country needs a credible resolution of these issues. If confirmed, I will not permit partisan politics, personal interests, or any other improper consideration to interfere with this or any other investigation."
Congress and the public should be "be informed of the results of the special counsel's work," he will say.
"For that reason, my goal will be to provide as much transparency as I can consistent with the law. I can assure you that, where judgments are to be made by me, I will make those judgments based solely on the law and will let no personal, political, or other improper interests influence my decision," he will say.
Barr will also pledge to continue enforcing the four priorities at the Justice Department, including fighting violent crime, prosecuting hate crimes, enforcing and improving immigration laws, and protecting the right to vote and the integrity of elections, according to the prepared testimony.
Barr is scheduled to testify Tuesday morning before the Senate Judiciary Committee.
In his prepared testimony, Barr says his memo "was narrow in scope," regarding "a specific obstruction-of-justice theory under a single statute that I thought, based on media reports, the special counsel might be considering."
His memo, Barr will say, did not address Mueller's investigation otherwise, "nor did it address other potential obstruction-of-justice theories or argue, as some have erroneously suggested, that a President can never obstruct justice."
