Manafort faces trial on bank fraud and other financial charges in the Eastern District of Virginia beginning July 25. Until now, there had been no indication that his role in the Trump campaign would become part of the trial, and he had asked the judge to keep details about his ties to President Donald Trump out of the trial. Prosecutors say any alleged collusion with the Russian government won't come up at the trial.

The allegation of a possible quid pro quo came amid several court filings Friday as both sides count down the remaining weeks until the trial. While prosecutors filled in the Trump campaign details, Manafort's team was busy filing requests with the judge to move his trial location and date, to look into possible leaks from the prosecutors and to keep Manafort out of the public eye.
