I think Michael floated the idea of moving Klingman out well before Johnny Ola's meeting with him.
No question about it. Roth sent Ola to Tahoe to tell Michael he had permission to move Klingman out. Roth benefited by this because it kept up the facade of their friendship and Roth thought Michael would be dead that very night in any case.
