As expected, special counsel Robert Mueller filed a criminal charge against Ex-Trump campaign manager Paul Manafort on Friday.

Manafort has responded to the allegations that he tampered with witness evidence.

In court filings, Manafort called the charges “dubious.”

Manafort’s lawyers also claimed that he cannot tamper with witnesses evidence because he doesn’t know who Special Counsel Robert Mueller will call as a witness.
