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.

The order against the firm, which did work for Democrats during the 2016 campaign, represents an escalation of efforts to punish groups the president sees as aiding his enemies.

U.S. President Donald Trump on Thursday signed an executive order suspending security clearances for employees of law firm Perkins Coie and targeting the firm's business with federal contractors, citing its diversity practices and political activities.
