Marco Rubio and Mike Lee, two GOP senators, introduced an amendment to the Republican tax bill on Wednesday.

The amendment would make the child tax credit more generous, but it would also cut the corporate tax rate to only 22% instead of the 20% proposed in the current tax bill.

President Donald Trump has said the 20% corporate rate is his one red line in the tax bill.

Republican Sens. Marco Rubio and Mike Lee announced an amendment to the GOP tax plan that would increase the tax breaks for families with children at the expense of corporations.

The pair released their amendment on Wednesday, saying the change was “a chance to do better by working families in this tax bill.” It is unclear how much support the amendment has on Capitol Hill, but it is unlikely to go over well in the White House.

The amendment would pay for the expansion of the child tax credit by reducing the federal corporate tax cut, lowering the rate to 22%. As written, Senate Republicans’ Tax Cuts and Jobs Act would cut that rate to 20% from the current 35%.

President Donald Trump has said the 20% rate is a red line, and Treasury Secretary Steven Mnuchin has said the corporate rate staying at 20% is “the president’s number one issue that is not negotiable.”

A White House official told Bloomberg on Wednesday that Trump would oppose the amendment. Sarah Huckabee Sanders, the White House press secretary, didn’t immediately respond to a request for comment.

Rubio and Lee, in their statement, argued the amendment was written to ensure enough tax benefits were going to families instead of corporations.
