Allies of President Donald Trump have been quick to threaten primary challengers for Republican senators who don't back Trump's Cabinet picks and legislative priorities.

In an interview on NBC News’ “Meet the Press,” GOP Sen. Lindsey Graham expressed disagreement with the president’s decision to pardon those convicted of violent crimes.

Sen. Lindsey Graham, a top Trump ally, says the White House pardoning rioters who fought with police while storming the U.S. is “sending the wrong signal.”

Sen. Lindsey Graham said he plans to support Kash Patel, President-elect Donald Trump's pick to lead the FBI who has sparked controversy even among some former Trump officials.
