President-elect Donald Trump stunned Senate Republicans by announcing that he will nominate Florida Rep. Matt Gaetz as attorney general.

WASHINGTON (AP) — Donald Trump has had few defenders in Congress as reliable as Matt Gaetz, who has thundered at one prosecutor after another for perceived bias against the president-elect and emphatically amplified the Republican’s rallying cry that the criminal investigations into him are “witch hunts.”

The Republican Party secured control of the House, giving the G.O.P. a governing trifecta in Washington to enact Mr. Trump’s legislative agenda. Mr. Trump also confirmed that Senator Marco Rubio was his choice to be secretary of state and said he had offered Tulsi Gabbard the job of director of national intelligence.
