President Donald Trump signed an executive order Thursday suspending the security clearances of employees at Perkins Coie, citing the law firm’s diversity, equity and inclusion practices.

Arpita Bhattacharyya and Robert McCauley joined Perkins Coie as partners in its intellectual property and patent litigation practices in Palo Alto, Calif., the firm announced Monday.

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.
