After midnight Wednesday, Senate Republicans pushed through a massive tax bill that will slash the corporate tax rate from 35 percent to 21 percent, temporarily reduce individual taxes, and eliminate the individual mandate under the Affordable Care Act in 2019, which will result in the loss of health care for 13 million Americans over the coming years.

The tax bill is the most unpopular piece of legislation in the last 30 years. After years of railing against raising the deficit under President Barack Obama, Republicans will add roughly $1 trillion to the national deficit with this legislation, according to the Joint Committee on Taxation.

No Senate Republicans voted against the tax bill.

House Minority Leader Nancy Pelosi (D-CA) blasted the tax bill as “simply theft — monumental, brazen theft from the American middle class and from every person who aspires to reach it.”

If the bill passes the House again later Wednesday morning, following a parliamentary stumble yesterday, President Trump is expected to sign the bill into law in the afternoon.

The United States Senate just passed the biggest in history Tax Cut and Reform Bill. Terrible Individual Mandate (ObamaCare)Repealed. Goes to the House tomorrow morning for final vote. If approved, there will be a News Conference at The White House at approximately 1:00 P.M. — Donald J. Trump (@realDonaldTrump) December 20, 2017

The tax bill marks Trump and the Republicans' only major legislative victory of 2017. Democrats are already pledging to work toward repealing the content of the bill if they are successful in retaking Congress in 2018.
