Trump hit another major law firm that worked for his political rivals with an executive order seeking to limit its ability to work for the U.S. government.

President Donald Trump on Thursday signed an executive order to suspend security clearances for Perkins Coie lawyers, as he continues to retaliate against law firms connected to his political opponents.

Trump says he's suspending security clearances of lawyers at Perkins Coie, which was involved in launching oppo research during the 2016 campaign into any ties between Trump and Russia.
