This is batshit crazy.
Turns out Manafort met with Assange multiple times in the Ecuadorian embassy in London. This was in 2013, 2015, and 2016 - while he was chairman of the Trump Campaign. Assange has also had Russian government officials visit him in London.
Seems this was mentioned in the Steele dossier, and now has been confirmed.
This is why Mueller is saying Manafort is lying during the investigation, and why Mueller is now saying Manafort violated their arragenment.
