President Donald Trump suggested Saturday he may be willing to negotiate changes to a significant portion of the tax overhaul, the corporate tax rate, injecting an element of uncertainty into the tax plan only hours after it cleared the Senate.

Trump told reporters at the White House before a trip to New York City that he would consider setting the corporate tax rate at 22 percent, compared to a 20 percent rate that he has pushed for with House and Senate Republicans during the fall.

Pointing to expected talks between House and Senate negotiators this month, Trump predicted "something beautiful is going to come out of that mixer" and the business tax would come "all the way down from 35 to 20. It could be 22 when it comes out, but it could also be 20. We'll see what ultimately comes out."

Trump spoke after the Senate approved a $1.5 trillion tax bill early Saturday that would rewrite the nation's tax code, cut individual rates and slash the corporate tax rate from 35 percent to 20 percent beginning in 2019. If enacted, the bill would provide the most sweeping changes to the tax system in three decades and help Trump deliver the first major legislative win of his presidency.
