A judge ruled Wednesday that the plea deal from Paul Manafort with special prosecutors has been voided because he lied to the FBI, among others.
Judge Amy Berman Jackson ruled that Manafort "made multiple false statements to the FBI, the OSC and the grand jury concerning matters that were material to the investigation."
The former Trump campaign manager had been convicted of financial crimes and then plead guilty in other charges and vowed to cooperate with federal prosecutors.
Judge Jackson said that he had lied at least three times, and on subjects that were "material to the investigation."
One of those instances had to do with Manafort's interactions with Konstantin Kilimnick, a Ukrainian national trained by the Russians and with a background in Russian intelligence.
Manafort has claimed that he never intentionally lied.
President Donald Trump has downplayed the role that Manafort had during his short tenure as his campaign manager in 2016.
"Paul Manafort worked for Ronald Reagan, Bob Dole and many other highly prominent and respected political leaders. He worked for me for a very short time," the president tweeted in 2018. "Why didn't government tell me that he was under investigation."
"These old charges have nothing to do with Collusion - a Hoax!" he added.
Prosecutors will be filing sentencing memos for Manafort on February 22. Since the judge has ruled that his plea agreement has been voided, his sentencing for the crimes he has admitted to may worsen significantly.
