Senate Majority Whip John Barrasso (R-WY) held firm to his conservative principles when questioned about President Donald Trump’s suggestion of a potential tax hike on the wealthiest Americans.

During the latest episode of Meet the Press, NBC’s Kristen Welker pressed the top Senate Republican on Trump’s recent remarks, in which the president said he would be “OK” with raising taxes on high-income earners to benefit lower- and middle-income workers as part of his “big, beautiful bill”—though he acknowledged that “Republicans should probably not do it” due to the potential political fallout.

“I want to talk about the president’s tax bill. In order to get some of the savings needed to pass it, President Trump floated the idea of increasing taxes on the highest income earners, those making more than $2.5 million. He also acknowledged the politics are quite thorny, but, senator, would you support that? Increasing taxes on the highest income earners?” Welker asked.

“Well, I’m a conservative, and I don’t want to increase taxes on anybody,” Barrasso replied. “What you do know is that the Democrats, if we don’t get this bill passed, they’re going to raise taxes by $4 trillion on the American people. It will hit every working family in America with higher taxes. And you know, 84% of Americans don’t like what the Democrats are proposing. Our goal is to keep more money in people’s pockets so they can go to the store, pay their rent, save for retirement. That’s what our focus is — lower costs and higher wages.”

Barrasso remained firm as Welker tried to clarify if he was excluding the possibility of raising taxes on the highest income earners.

“I oppose raising taxes on anyone, and the Democrats want to raise $4 trillion of taxes on everyone,” The Wyoming Republican reiterated.

He added later: “I am against raising taxes on anyone. We’re working the bill through the process. It’s going through the House. We’re ironing out the details right now. We’re going to get a bill passed and signed by the president that’s going to put more money in people’s pockets and give them the certainty that taxes aren’t going to go up.”
