A federal judge on Tuesday sentenced President Trump’s former deputy campaign chair Rick Gates to 36 months of probation and ordered him to serve 45 days in jail after he provided cooperation that helped the government win the convictions of Roger Stone and Paul Manafort.

Gates, 47, pleaded guilty in February 2018 to charges brought by special counsel Robert Mueller of lying to the FBI and the special counsel’s investigators and conspiracy against the United States.

“I wish to express to this court that I accept complete responsibility for my actions that have led me here,” Gates said before being sentenced. “I greatly regret the mistakes I have made.”

Gates appeared in Washington before Judge Amy Berman Jackson, who allowed him to serve his sentence on weekends or according to another agreement with probation officers.

He must also pay a fine of $20,000 a month for 20 months, and complete 300 hours of community service.
