House Speaker Mike Johnson, R-La., is no "big fan" of hiking the tax rate for America's wealthiest to 40%, an idea reportedly being mulled by Republicans to offset some costs of their in-progress tax package.

"We're the Republican Party, and we're for tax reduction for everyone, and that's a general principle that we always try to abide by," Johnson told Fox News' Maria Bartiromo on Sunday. 

Though there are many discussions, thoughts and theories on how to get all the GOP's goals accomplished, Johnson said he wouldn't "put any money on any of [those] yet."

"I would say just stay tuned. The next five to six weeks are going to be critical as all these negotiations happen in the committees of jurisdiction," he continued.

"You'll hear lots of rumors and lots of talk, but we'll see where it all lands."

Johnson voiced the need for consensus on the package, eyeing the 218 votes needed in the House and the 51 votes needed in the Senate for successful passage, assuring viewers that the bill will have reached an adequate "comfort level" before heading to the floor.

According to Bloomberg, the floated 39%-to-40% tax rate would affect those earning $1 million or more annually, a two-to-three percentage increase from the current 37% rate.

President Donald Trump floated moving nearly 90,000 IRS agents hired under the Biden administration to the border to patrol the area while armed with guns. 

"On day one, I immediately halted the hiring of any new IRS agents. They hired, or tried to hire, 88,000 new workers to go after you. And we're in the process of developing a plan to either terminate all of them or maybe we'll move them to the border. And I think we're going to move them to the border," Trump said during a rally at Circa Resort & Casino in Las Vegas on Saturday evening. 

"Where they're allowed to carry guns, you know, they're so strong on guns, but these people are allowed to carry guns, so we'll probably move them to the border," he continued. Certain special IRS agents are permitted to carry firearms as part of their duties, according to IRS Code, 26 U.S. Code § 7608. 

Trump joined supporters in Las Vegas this weekend after touring destruction in North Carolina left by Hurricane Helene in September, as well as California, where he toured Los Angeles and met with local leaders about the wildfires that have ripped through the area this month.

While floating moving the thousands of IRS agents to the border, Trump also suggested ending income tax across the board, saying his plans on tariffs could fill the financial gaps. 

"How about just no tax," he said to cheers, while he chuckled. "You could do that. You know if the tariffs work out like I think, a thing like that could happen, if you want to know the truth."

"Years ago, 1870 to 1913, we didn't have an income tax. We had, what we had is tariffs, where foreign countries came in and they stole our jobs, they stole our companies, they stole our product. They ripped us off. And, you know, they used to do numbers. And then we went to tariff, a tariff system. And the tariff system made so much money. It was when we were the richest from 1870 to 1930. Then we came in with the – brilliantly came in – with an income tax," he continued, explaining the Great Depression rocked the U.S. shortly after moving away from the tariff system of the 1800s and early 1900s.

Democrats in 2022 approved $80 billion in funding for the IRS, including to hire roughly 87,000 new agents across a 10-year period as part of the Inflation Reduction Act. President Joe Biden signed the legislation into law that year.

Trump's Vegas speech focused on taxes, hearkening back to his June campaign rally in the state when he first announced he would eliminate taxes on tips.

"Any worker who relies on tips [as] income, your tips will be 100% yours," Trump said on Saturday in the city that is run by service workers at flashy hotels and casinos and restaurants.

Trump also touted that a handful of his campaign promises are already unfolding into real results, including withdrawing from the World Health Organization (WHO) and dismantling some federal diversity, equity, and inclusion (DEI) practices.

"We got rid of the woke crap," Trump said Saturday. "A lot of crap… you know, these people were petrified of it. I'll tell you, these companies, they run these big companies, they were petrified of it."

EXCLUSIVE: A GOP lawmaker is seeking to significantly raise taxes on endowment profits being banked by private universities to align their levy with the current corporate tax rate.

Many private universities have invested funds for operational use that acquire interest each year, known as an endowment. In 2017, the Trump-era Tax Cuts and Jobs Act enacted a 1.4% tax on the interest private universities were receiving from these endowments. 

However, a new Republican bill would raise that tax to hold elite educational institutions to the same tax standard as corporations, which currently see a 21% corporate tax.

Rep. Troy Nehls, R-Texas, is expected to introduce legislation on Wednesday, the Endowment Tax Fairness Act, to raise the excise tax on annual private university endowment investment returns by nearly 20 percentage points, from 1.4% to 21%.

The GOP-backed bill would then require the revenue to be deposited into the General Fund of the Treasury, a fund managing the government's budget, to be used to reduce the national deficit. 

Nehls tells Fox News Digital he introduced the bill because elite universities should not have "far lower" taxes than working Americans.

"Elite private universities have accumulated and sit on massive university endowments and pay a tax less than 2% on the investment earnings of their endowments, which is far lower than what most hardworking Americans pay in taxes. Meanwhile, these universities have significantly increased tuition for America’s youth, which has overwhelmingly surpassed the average annual inflation rate," he said.

The tax would apply to private colleges and universities that meet certain requirements, such as institutions that have 500 or more students.

Additionally, universities that would be taxed are those that aggregate fair market value of assets of at least $500,000 per student and that have more than 50% of its student body located in the United States, according to the bill. 

Endowments subject to the tax, such as Harvard, Yale, Princeton and Columbia, reportedly hold a combined $270 billion of assets under management.

"This is unacceptable," Nehls told Fox. "My bill would put elite universities with massive endowments on notice by holding them to the same tax standard as corporations."

If passed, the tax would begin effective immediately after the date of the bill's enactment.
