Paul Manafort, the former campaign manager for US President Donald Trump, pleaded [court documents, PDF] guilty on Friday to conspiracy against the US and conspiracy to obstruct justice through witness tampering. 

Prosecutors originally brought seven charges against Manafort in the US District Court for the District of Columbia [official website], but they reduced [POLITICO report] the charges to only two.

The charges allege that Manafort acted as an agent of the Ukraine without properly registering as a foreign agent and that he had laundered money and committed tax evasion. Manafort had two cases pending against him—one in the DC federal court and another in a Virginia federal court.

As part of his plea deal, Manafort will have to assist Special Counsel Robert Mueller [official website] with his investigation into the 2016 presidential election. The plea deal also limits the prison sentence to 10 years and allows Manafort to serve both his Virginia and DC sentences at the same time.

Last month a jury in the Virginia federal court found [JURIST report] Manafort guilty on eight charges of fraud. The jury could not reach an agreement on an additional 10 charges, and the judge declared a mistrial.

Last week a court sentenced [JURIST report] former Trump campaign aide George Papadopoulos to prison for lying to the FBI. In August Trump’s former attorney Michael Cohen also pleaded guilty [JURIST report] to fraud.
