The order said it was intended to end government sponsorship of harmful activity at Paul, Weiss and specifically punish one of its former lawyers, Mark F. Pomerantz.
Mr. Trump mentioned Mr. Pomerantz by name in an angry speech Friday at the Justice Department, where he complained about prosecutors and private lawyers who pursued cases against him, calling them really bad people. Mr. Trump, in the same speech, claimed he was ending the weaponization of the Justice Department, though his move against the firm showed he will continue using his power to exact retribution on his opponents.
Mr. Pomerantz had tried to build a criminal case against Mr. Trump several years ago when he worked at the Manhattan district attorneys office. The White House announcement called Mr. Pomerantz an unethical lawyer who tried to manufacture a prosecution against President Trump.
The order also cited a case brought by a Paul, Weiss partner against pro-Trump rioters at the Capitol on Jan. 6, 2021, and the firms diversity policies as reasons for the restrictions.
A spokesperson for the firm said in a statement that Mr. Pomerantz retired from the firm in 2012 and had not been affiliated with it for years.
The actions cited by trump all occurred after Pomerantz had retired from the firm
