A federal judge today revoked bail for Paul Manafort and ordered Donald Trump's former campaign manager to jail to await his trial for violating federal lobbying laws.

Judge Amy Berman made the decision following allegations made last week by Special Counsel Robert Mueller that Manafort was involved in witness tampering. 

According to Mueller, Manafort tried to tell potential witnesses in his case to lie about his lobbying efforts.

Manafort had been under house arrest after posting a $10M bond. His trial is expected to begin in September.
