WEST PALM BEACH, Fla. — President-elect Donald Trump chose Rep. Matt Gaetz of Florida to serve as his attorney general on Wednesday, bypassing more experienced options in favor of a loyalist who has built a national reputation as a disruptor and whom Trump has tasked with dramatically overhauling the Justice Department.

Trump also announced that he had tapped Sen. Marco Rubio of Florida as his nominee for secretary of state. And he selected Tulsi Gabbard, a former Democratic member of Congress and presidential candidate, to serve as his director of national intelligence.
