As the dust begins to settle in the wake of the Senate impeachment vote to acquit President Donald Trump of two articles of impeachment brought against him by the Democrat-led House, one of his former friends on the other side of the political aisle is starting to feel the heat for voting to convict the president.

According to The Hill, West Virginia Sen. Joe Manchin, who has sided with Trump on more than one occasion, joined his party and voted “guilty” on the articles of impeachment and realized this week that Trump isn’t happy with his decision whatsoever.

“Can’t say I mind the fact that the great people of West Virginia are furious at their puppet Democrat Senator, Joe Manchin,” Trump tweeted on Saturday. “They will never forget his phony vote on the Impeachment Hoax. All he had to do is read the Transcripts, sadly, which he wouldn’t understand anyway.”

Trump went on to continue his slam against Manchin in another tweet while also taking a shot at Utah Republican Sen. Mitt Romney for siding with Manchin and the Democrats on the matter of impeachment.

“But, just like the people of West Virginia will no longer look at weak & pathetic Joe Manchin the same (I got the Pension Bill approved, Manchin couldn’t do it), the wonderful people of Utah will never look at “grandstander” Mitt Romney with anything but contempt & disgust!” Trump tweeted.

Manchin, who worked with the president to get an important pension bill passed for his state, attempted to defend his position on impeachment and his work for the people of West Virginia in a tweet not long after the president attacked him.

“Trump – no Democrat has worked harder in a bipartisan way in the hopes that you would succeed. The people of WV know exactly who has worked day & night for the last 5 years to secure their healthcare & pensions & it wasn’t you,” Manchin replied.

The senator went on to claim that after he read the transcript and heard the case against the president, he essentially had no choice but to enter a “guilty” vote last week. Manchin also slammed the president for the Republicans’ choice to shoot down a vote that would have made it possible to call witnesses and documents in the Senate impeachment trial.

“I’ve read the transcripts thoroughly & listened to the witnesses under oath. Where I come from a person accused defends themselves with witnesses and evidence,” Manchin wrote.

While all Democrats voted for Trump’s conviction and removal from office in the Senate impeachment vote, Manchin was one of a handful of “red state” senators who risked upsetting their constituents by voting Trump guilty.

Trump won West Virginia in 2016 and is expected to do so again in the 2020 presidential election.
