President Donald Trump's former campaign chairman Paul Manafort is going to jail.

On Friday, Manafort was ordered into custody after a federal judge revoked his house arrest, citing newly filed obstruction of justice charges. The move by U.S. District Judge Amy Berman Jackson made Manafort the first Trump campaign official to be jailed as part of special counsel Robert Mueller's investigation.

"So this is a first Trump campaign aide to actually be put in jail as part of the special counsel's investigation, said Chad Day, a reporter with The Associated Press.

"Now, of course, this case doesn't deal directly with Russian election interference but still, this is the first time that we've seen someone who was close with Donald Trump during the campaign, as Paul Manafort was, and who actually led the campaign during several key months, and be sent to jail, Day said.  

Already under intense pressure to cooperate with prosecutors in hopes of securing leniency, Manafort now loses the relative freedom he enjoyed while he prepared for two criminal trials in which he faces the possibility of spending the rest of his life in prison.

In issuing her ruling, Jackson said she had "struggled" with the decision but she couldn't "turn a blind eye" to his conduct.

"Manafort's attorneys had argued that these were innocuous contacts, and that he actually didn't know that the people he had contacted were witnesses," Day said.

"The prosecution had countered that that's actually not a defense to witness tampering, and that it was, as they said, inconceivable that he didn't know that these people would be people that the prosecution would want to talk with," he said.

A federal grand jury indicted Manafort and a longtime associate, Konstantin Kilimnik, last week on charges of obstruction of justice and conspiracy to obstruct justice.

Manafort, 69, and Kilimnik are accused of attempting to tamper with witnesses in the case by trying to get them to lie about the nature of their Ukrainian political work. Prosecutors say Manafort and Kilimnik tried to get the two witnesses to say that lobbying work carried out by clandestinely paid former politicians only occurred in Europe and not the U.S., a contention the two witnesses said they knew to be false.

The distinction matters because unregistered foreign lobbying in the U.S. is a crime, while lobbying solely in Europe would be outside the special counsel's jurisdiction.

Manafort also pleaded not guilty to the latest indictment on Friday. Kilimnik, who prosecutors say is living in Russia, did not appear in court. Mueller's team has said that Kilimnik has ties to Russian intelligence agencies, a claim he has previously denied.

Manafort will remain in jail while he awaits trial in both Washington and Virginia over the next few months. He faces several felony charges - including tax evasion, bank fraud, money-laundering conspiracy and acting as an unregistered foreign agent - related to his Ukrainian political work, money he funneled through offshore accounts and loans he took out on property in the U.S.

Now of course this is while he awaits trial and so he hasn't been convicted of anything at this point. But what the judge found was that there is probable cause that he had committed these crimes citing the grand jury indictment and that she couldn't, you know, she couldn't trust that he would not violate her order going forward."

"The main thing that this does is it ratchets up the pressure on Paul Manafort to cooperate with prosecutors.  At this point, you know he's been fighting this case pretty vigorously, both here and also in a subsequent case in Virginia. And so, you know it's yet to be seen what--what impact this will have on his calculus of whether or not he should reach out to prosecutors and perhaps try to make some kind of deal. Now why that matters for the president, it's yet to be seen. You know Paul Manafort was a key part of the campaign. He also took part in a meeting--a Trump Tower meeting in June 2016 with a Russian attorney who is supposed to be peddling dirt on Hillary Clinton, and he would be a witness to a lot of the aspects of the campaign that they are probing as part of the larger Russia investigation.

"So we're here at the federal courthouse in Washington where a federal judge just issued an order that jailed Paul Manafort, President Donald Trump's former campaign chairman. Now the reason for this was that last week a federal grand jury here in Washington returned an indictment against him that accused him of obstruction of justice, particularly witness tampering. And so today the judge ruled that she could not find or craft any kind of order that would ensure that he would not continue to commit crimes while he was remaining out on house arrest. And so during this hearing today she took a brief recess considered it and came out and said that he in fact has to go to jail."
