The war of words between Sen. Joe ManchinJoseph (Joe) ManchinDoug Jones to McConnell: Don't 'plow right through' with Kavanaugh Cook Political Report moves Texas Senate race to ‘toss-up’ The Memo: Tide turns on Kavanaugh MORE (D-W.Va.) and Vice President Pence intensified Thursday, with Manchin saying Pence's attacks against him prove the Trump administration isn't actually interested in reaching across the aisle.

"My record speaks for itself. If they’re attacking people like me then they don't want bipartisanship. They are not committed or sincere about making government work," he said. 

Manchin, viewed as one of the Senate's most moderate senators, noted that he's voted with the Trump administration 54 percent of the time and "there isn’t another person in Congress who votes as bipartisan as I do."

Manchin's latest statement comes after Pence told Politico, in an interview that ran on Thursday morning, that he would campaign against Sen.

"We’re going to spend a fair amount of time in the states that the president carried very strongly — Indiana being one of them, West Virginia here being another, places like Montana, elsewhere around the country we think represent a real opportunity for us,” he told the publication

The two men also traded rhetorical volleys on Wednesday after Pence tweeted from his White House account that he urged Manchin to support the GOP tax plan "but #JoeVotedNo."
Manchin — who said on Wednesday night that Pence's comments are part of "why Washington sucks"— added on Thursday that Pence and his team decided for the tax bill to be "strictly partisan" and tried to take health care away from roughly 200,000 West Virginians. 
"Mike Pence talks a good game as far as bipartisanship but I met with their team 21 times to make tax cuts larger [and] permanent for the middle class, not big businesses and millionaires. They decided to be strictly partisan instead of helping the middle class West Virginians," he said in a tweet. 
He's touted his relationship with Trump and was reportedly considered for a Cabinet position. 
Manchin noted on Thursday that the president called him last week and invited him to the White House "to talk about ways we can work together on immigration reform."
