Senator Ted Cruz said the newly passed Republican tax bill will make everyone's taxes go down with the exception of "rich people in Manhattan and San Francisco."

The GOP lawmaker made the remarks on the Senate floor Tuesday in a speech supporting Republicans' sweeping tax overhaul plan, considered to be the most comprehensive rewrite of the nation's tax laws in more than 30 years. The bill cleared the House on Tuesday and the Senate early Wednesday.

Cruz's home state of Texas ranks just behind New York and California in the number of billionaire residents.

Cruz said:

"The only people whose taxes are going up are the really rich. The middle class, their taxes are all going down. The working class, their taxes are going down. Every taxpayer, their taxes are going down. Except rich people in Manhattan and San Francisco, some of them, their taxes may go up."

The senator's camp did not immediately respond to SFGATE's request for comment.

The $1.5 trillion tax package will provide large cuts for corporations and the wealthiest of Americans and smaller breaks for middle- and low-income families.

Trump called the journey to the overhaul "an amazing experience."

"It's always a lot of fun when you win," he said.
