Former Trump campaign chairman Paul Manafort has tentatively agreed to a plea deal with special counsel Bob Mueller to avoid his upcoming trial, ABC News reports.

The deal is expected to be announced in court Friday.

It is unclear if Manafort has agreed to cooperate with the investigation or is simply “conceding to a guilty plea,” ABC News reported.

Manafort’s second trial was expected to begin later this month in Washington DC. Last month, he was convicted of eight of 18 counts in a Virginia federal court and faces up to 80 years behind bars as he awaits sentencing.

He has been held in jail since prosecutors accused him of witness tampering earlier this month.

Manafort, who previously worked for Russian-backed oligarchs in Ukraine, joined the Trump campaign in March 2016 and worked for free despite reportedly being millions in debt to one of Russian President Vladimir Putin’s closest associates.
