Senator Lamar Alexander says there was a “mountain’ of evidence” in the impeachment, but doesn’t feel the need to hear from witnesses. The Tennessee Republican released a statement saying:

“I worked with other senators to make sure that we have the right to ask for more documents and witnesses, but there is no need for more evidence to prove something that has already been proven and that does not meet the United States Constitution’s high bar for an impeachable offense.” 

Yet he acknowledges what Donald Trump was wrong:

“It was inappropriate for the president to ask a foreign leader to investigate his political opponent and to withhold United States aid to encourage that investigation. When elected officials inappropriately interfere with such investigations, it undermines the principle of equal justice under the law. But the Constitution does not give the Senate the power to remove the president from office and ban him from this year’s ballot simply for actions that are inappropriate.”

Instead, he thinks this should be decided at the ballot box.

“The question then is not whether the president did it, but whether the United States Senate or the American people should decide what to do about what he did. I believe that the Constitution provides that the people should make that decision in the presidential election that begins in Iowa on Monday.”

After Alexander’s decision #Coward and #LamarAlexanderIsACoward became the #1 trending topic on Twitter.
