Russian President Vladimir Putin was waiting on a "wink" from former U.S. President Donald Trump to seize parts of Ukraine—years before Russia launched a full-scale invasion—according to a new interview. Written correspondence between former Trump campaign chair Paul Manafort and Kremlin aide Konstantin Kilimnik discussed Putin claiming part of Ukraine, saying that a "wink" from the Republican former president was needed to "make this work," former Mueller prosecutor Andrew Weissmann has said. Speaking with PBS' Firing Line and host Margaret Hoover, Weissmann said this was "such a clear indication of what Vladimir Putin was trying to do."
