The $2.25 trillion plan unveiled this week by Biden takes direct aim at former President Trump’s signature economic achievement by raising the corporate tax rate that Republicans lowered in their 2017 Tax Cuts and Jobs Act.

“It’s pretty clear the way it is being crafted is far-left and goes after the marquis item that we passed on taxes,” said a Senate Republican aide.

Biden’s proposal “fundamentally takes the approach that government and government spending is the answer, and we strongly disagree with that,” the aide said…

Senate Republican aides say it’s “highly unlikely” that any GOP senators will vote for Biden’s plan, noting that even a key moderate like Collins is allied with the party’s core position of favoring lower taxes.

Collins reportedly laughed when asked last month how Senate Republicans would react to proposals from the White House that raise taxes.
