Trump made the announcement while departing the White House for a trip to Missouri Friday.
Trump says that Barr is “a terrific man” and “one of the most respected jurists in the country” and says, “I think he will serve with great distinction.”
He also says Barr was his “first choice from Day One.”
If confirmed by the Senate, Barr would succeed Attorney General Jeff Sessions, who was forced out by Trump in November. Sessions’ chief of staff, Matthew Whitaker, is currently serving as acting attorney general.
Trump also confirmed he would nominate State Department spokeswoman Heather Nauert to be the next U.S. ambassador to the United Nations. Trump previously said Nauert was under serious consideration to replace Nikki Haley, who announced in October that she would step down at the end of this year.
