For his next trial, but talks broke down. Via the WSJ:
The plea discussions occurred as a Virginia jury was spending four days deliberating tax and bank fraud charges against Mr. Manafort, the people said. That jury convicted him on eight counts and deadlocked on 10 others. Prosecutors accused Mr. Manafort of avoiding taxes on more than $16 million he earned in the early 2010s through political consulting work in Ukraine.
The plea talks on the second set of charges stalled over issues raised by Special Counsel Robert Mueller, one of the people said. It isn’t clear what those issues were, and the proposed terms of the plea deal couldn’t immediately be determined.
[…] The plea discussions on the Washington case represent a softening in posture for Mr. Manafort, who has fought charges brought by Mr. Mueller’s 15-month investigation longer and more aggressively than other defendants in the probe.
[…] Prosecutors have until Wednesday to report whether they plan to retry Mr. Manafort on the deadlocked counts. For now, both sides appear to be preparing for the Washington trial.

Manafort needs to go deep underground in order to survive what with owing the Russian Mafia millions of dollars.
Perhaps Mueller is unwilling to stick him in the witness protection program? Or they couldn’t agree on a location?
Manafort’s goose is cooked whether or not he’s pardoned by Trump.
