Sen. Ron JohnsonRonald (Ron) Harold JohnsonSunday shows preview: Supply chain crisis threaten holiday sales; uncertainty over whether US can sustain nationwide downward trend in COVID-19 cases Democratic incumbents bolster fundraising advantage in key Senate races Most Senate Republicans don't want to see Trump run again MORE (R-Wis.) said on Wednesday that he will not support the Senate GOP tax plan, becoming the first GOP senator to say he will oppose the proposal.
“If they can pass it without me, let them,” Johnson told The Wall Street Journal. “I’m not going to vote for this tax package.”
Senate Republicans have a narrow path to clearing the tax plan. With a 52-seat majority, if every Democrat votes no, they can only afford to lose two GOP senators and still have Vice President Pence break a tie.
Johnson confirmed in a statement that he currently opposes both the House and Senate tax plans, which, he argues, do not do enough to help "pass-through entities."
"These businesses truly are the engines of innovation and job creation throughout our economy, and they should not be left behind," Johnson said. "[I] look forward to working with my colleagues to address the disparity so I can support the final version.”
The Senate bill allows individuals to deduct 17.4 percent of income from pass-through businesses, and pass-through related provisions were updated in the modified bill released Tuesday night so that more income could qualify for the deduction.
But those tax breaks are temporary, compared to permanent cut to the corporate tax rate.
Johnson added to The Wall Street Journal that he has concerns about the proposal and that writers of the tax bill have been unreceptive to his input.
“I don’t like that process,” Johnson said. “I find it pretty offensive, personally.”
Johnson noted he has been trying to get hearings from both the Senate Finance Committee, which wrote the Senate bill, and the House Ways and Means Committee, but has been rebuffed by party leadership.
"It’s not like I’m just coming out of the woodwork all of a sudden raising it. I’ve been talking to my colleagues a long time. I presented my idea months ago," Johnson said.
Johnson's opposition to the tax plan is the latest hurdle for Republicans as they try to get a bill to President Trump's desk by the end of the year.
The Senate Finance Committee is expected to vote on the bill this week, with a full Senate vote expected after the week-long Thanksgiving recess.
As part of the vote-a-rama — an hours-long floor session — Johnson would be able to force a vote on any potential changes he wants to the tax plan.
Though Johnson is the first GOP senator to formally say they will oppose the current version of the proposal, other GOP senators have raised concerns about the plan.
