]>> Here we go.>> US Federal prosecutors accused Donald Trump's ex-campaign chairman of witness tampering on Monday. In court filings, a team working for Special Counsel Robert Mueller say Paul Manafort tried to contact witnesses in his own tax fraud and lobbying case. Manafort has already been indicted by Mueller, who's investigating possible collusion between the Trump campaign and Russia.
Monday's court filing says Manafort's outreach was a violation of his release while he awaits trial. Mueller asked a Federal Judge to revise the terms of Manafort's release or revoke it entirely. He also urged the judge to schedule a hearing on the matter, which could end with Manafort going to jail.
The filings say Manafort tried to call text and send encrypted messages to two people from the Hapsburg group, a firm he worked with to promote the interest of Ukraine. An FBI special agent wrote that the communication with witnesses was quote, in an effort to influence their testimony and to otherwise conceal evidence.
Manafort is the most senior member of Trump's campaign to be indicted, however the charges don't relate to campaign activities. They range from money laundering and failing to register as a foreign agent, to bank and tax fraud. Manafort has pleaded not guilty. Trump himself has denied collusion with Russia, and repeatedly called Mueller's investigation a witch-hunt.
