And the word trending alongside his name wasn’t exactly a compliment:

HuffPost

House impeachment managers have been pressing senators to allow testimony from former White House national security adviser John Bolton, who could speak to Trump’s attempts to use U.S. military aid to pressure Ukraine into investigating his political rivals. Bolton’s upcoming book reportedly confirms many of the details.

Alexander was considered the swing vote and his decision will likely ensure that no witnesses will be called. However, he argued witnesses would be irrelevant. Trump’s actions, he said, were “inappropriate,” but not bad enough to warrant removal from office.

“Let the people decide” via this year’s presidential election, Alexander wrote.

That didn’t sit well with his critics, who slammed the decision on Twitter and caused “coward” to trend along with Alexander’s name:

The fix is in.

No witnesses.

Lamar Alexander and his Republican colleagues have forever shamed the United States Senate. This is a very dark moment in our history — Joe Lockhart (@joelockhart) January 31, 2020

“The president’s conduct is a national embarrassment.... All he has to do is give us a day of honesty, to come out and say this is what happened.”

Lamar Alexander released a statement befitting oof the coward Republican that he is:



Trump is guilty as charged, but I won’t apply the law.



Three quarters of Americans want #WitnessesNOW and expect John Bolton to testify.



But the @SenateGOP is coward central. — Grant Stern (@grantstern) January 31, 2020
