William Barr, President Donald Trump's nominee for U.S. attorney general, will seek to persuade senators Tuesday that he'll protect special counsel Robert Mueller III's investigation from political interference, according to his written remarks released by the Justice Department.

“If confirmed, I will not permit partisan politics, personal interests, or any other improper consideration to interfere with this or any other investigation,” Barr will tell senators, according to his prepared testimony. “I will follow the Special Counsel regulations scrupulously and in good faith, and on my watch, Bob will be allowed to complete his work.”

Barr, of counsel at Kirkland & Ellis, will field questions from the Senate Judiciary Committee beginning Tuesday as part of his two-day confirmation hearing. Among the host of questions he will face, one topic is sure to dominate the rest: the fate of the special counsel probe and a final report on its findings.

The nominee, who previously served as U.S. attorney general from 1991 to 1993, is expected to assume oversight of Mueller's investigation. In his remarks, Barr said he believes it is “very important” that the public and lawmakers are informed of the “results” of the special counsel's work.
