President Trump on Tuesday signed an order targeting a law firm that previously employed Andrew Weissman, a former federal prosecutor who worked on then-special counsel Robert Mueller’s team.

The order, which targets the law firm Jenner and Block, is the latest move from Trump to punish major firms with ties to critics and individuals he holds grudges against.

White House staff secretary Will Scharf alleged the firm had engaged in “weaponization of the legal system against American principles and values.”

“And Andrew Weissman is the main culprit with respect to this firm?” Trump asked, calling Weissman a “bad guy.”

Scharf said Weissman was “one of a number of reasons” the order was being issued.

The text of the order was not immediately available, but Trump has signed multiple orders in recent weeks targeting security clearances and government contracts for major law firms with ties to lawyers who represented Democrats or worked on cases involving Trump.

Jenner and Block did not immediately respond to a request for comment.
