Paul Manafort, the former campaign chairman for Donald Trump's 2016 campaign, appeared in a sealed federal courtroom on Monday, according to Bloomberg.

U.S. District Judge Amy Berman Jackson is considering whether Manafort lied to investigators after pledging to cooperate with Special Counsel Robert Mueller. Prosecutors will reportedly be presenting secret government evidence.

Reporters were ejected from the courtroom before the hearing began. "Thick loose-leaf binders could be seen near lawyers for the government and Manafort before the courtroom was sealed," Bloomberg reported.

"They've covered the little windows on the doors so you can't see in. A redacted transcript will come out after," said Zoe Tillman, a reporter for BuzzFeed News.

Mueller has alleged that Manafort violated his plea agreement by lying to investigators. But Manafort denies the allegations, insisting any misstatements were due to lapses in memory.
