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.”

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.

The South Carolina Republican told CNN that he “did not like” how Trump pardoned people who “beat up cops,” and suggested he would be open to curtailing the presidential pardon power.
