President Trump escalated his fight with the legal industry by issuing an executive order aimed at Paul Weiss, one of the country’s top law firms.

We revoked the clearances of deranged Jack Smith, Alvin Bragg, Letitia James and the crooked law firms that aided their partisan persecutions,” Trump said at a speech at the DOJ headquarters on Friday.

The president’s use of government power to punish firms is seen by some legal experts as undercutting a basic tenet: the right to a strong legal defense.
