If it is of importance today that Ukraine is beholden to the president and the American administration for help, was it not at least equally important in 2016? I have no problem with the principle that the president should not exploit his power over foreign relations for partisan political purposes. I have a problem with the double standard.

See the way the game is played: When the Obama administration leans on Ukraine for help in an investigation of political opponents, the Democrats and the media say, “But look how corrupt Paul Manafort was!” When the Trump administration leans on Ukraine for help in an investigation of political opponents, the Democrats and the media say, “Abuse of power — impeach him!”
