Trump is being impeached because there was no public purpose for his Ukraine policy. Trump defenders claim that Trump was promoting U.S. interests by demanding an investigation of corruption. President Richard M. Nixon was guilty of abusing his authority, but he didn’t subordinate foreign policy to his personal political interests as Trump has. (He did secretly urge South Vietnam not to join peace talks in 1968 to aid his campaign, but he wasn’t president then.) And she was neither president nor even secretary of state at the time; her actions, therefore, had no impact on U.S. foreign policy.
