President Donald Trump's former campaign chairman, Paul Manafort, has dropped the law firm that was representing him in the investigation led by special counsel Robert Mueller.

Manafort spokesman Jason Maloni says in a statement that Manafort is no longer represented by Washington law firm WilmerHale. Maloni says Manafort will be represented by Miller & Chevalier. The firm has specific expertise in international tax cases.

Politico reported, citing sources familiar with the matter, that the new firm specializes in complicated financial crimes among other issues.

One of Manafort's homes was recently raided by FBI agents carrying a warrant that sought tax documents and records related to foreign bank accounts.

Manafort had been represented by Reginald Brown of WilmerHale. Brown declined to comment in a text message to The Associated Press.
