Mark my words: Trump witness-tampered with Manafort directly/indirectly. Manafort had nothing to lose by cooperating with Mueller—only gain—and Mueller was asking him about Trump, and Manafort lied. So he was expecting a pardon. Which means somebody let him think it could happen.
2/ When all you have to do is *tell the truth*, and if you don't it could give you *many more years in prison*—to the point of making your sentence a *life sentence*—what would it take to get you to lie? There aren't many possibilities beyond the promise of a presidential pardon.
3/ And let's be clear (and I say this from experience): Manafort's lawyers would've *explicitly and repeatedly* told him *not to lie* to Mueller. So Manafort had to be getting entreaties from *other sources* besides his lawyers to make him agree to lie to Mueller about collusion.
