ALEXANDRIA, Va. Rick Gates , once a top aide to President Donald Trump s former campaign chairman Paul Manafort , admitted Tuesday to a wide variety of crimes, including embezzling money from Manafort to fund an extramarital affair about a decade ago.

Gates is the star witness for prosecutors in the case against Manafort, who is currently on trial for money laundering and fraud charges stemming from his work for pro-Russian political forces in Ukraine. Gates is cooperating with the team of special counsel Robert Mueller.

The Secret Life Of Rick Gates

On Gates second day of testimony, Manafort attorney Kevin Downing confronted the witness about the secret life of Rick Gates. Gates admitted to another relationship and that he maintained a flat in London and took the woman on trips around Europe. He said the affair took place about 10 years ago.

Gates, who admitted to a staggering amount of criminal activity on the stand, testified that he was living beyond my means and engaged in financial crimes to fund his lifestyle. The father of four from Richmond made a salary of $240,000 from Manaforts company, but also took home bonus money and inflated expense reports to the tune of hundreds of thousands of dollars.

Pressed by Downing, Gates at first tried to avoid saying that he embezzled money from Manafort. When Downing used the word embezzled, Gates would instead say he took unauthorized reimbursements. He eventually relented.

It was embezzlement from Mr. Manafort, Gates testified.

Gates credibility is a key issue for the defense.

Manaforts lawyers are trying to make a case that jurors simply cant believe the testimony of an admitted liar and criminal.

Have they confronted you with so many lies that you cant remember all of it? Downing asked at one point.

But many of the crimes Gates said he committed on Manaforts behalf were documented, meaning that jurors wont have to rely solely on Gates word.

Im here to tell the truth, Gates told jurors. Mr. Manafort had the same path. Im here ... I am trying to change.

On Monday, Gates had already publicly admitted to committing crimes with Manafort, including falsifying tax documents and hiding his lobbying work.

Much of his testimony on Tuesday morning detailed the various schemes he engaged in for Manafort. Gates said he was working on Manaforts orders when he used overseas accounts to pay for Manaforts personal expenses, including luxury clothing, landscaping and audio-visual costs.

Gates also created fake invoices to send to an overseas bank, he said, because the bank needed the invoices to list their lobbying business as the client rather than Manafort himself, even though the expenses were for Manafort personally.
