Manafort worked for a corrupt President Yanukovych. Ukrainians MPs and journalists exposed some of this corruption. Why is @RudyGiuliani dragging Trump into this? & Ukrainians no longer can expose corruption their own country? Very weird position Giuliani is staking out here. https://t.co/F03FZcI1mz— Michael McFaul (@McFaul) May 11, 2019
