The grave question the Constitution tasks senators to answer is whether the president committed an act so extreme and egregious that it rises to the level of a high crime and misdemeanor.
Yes, he did.
The president asked a foreign government to investigate his political rival. The president withheld vital military funds from that government to press it to do so. The president delayed funds for an American ally at war with Russian invaders. The president’s purpose was personal and political. Accordingly, the president is guilty of an appalling abuse of public trust.
What he did was not “perfect.” No, it was a flagrant assault on our electoral rights, our national security, and our fundamental values.
Corrupting an election to keep oneself in office is perhaps the most abusive and destructive violation of one’s oath of office that I can imagine.
