Two top Trump administration officials said it may not bepossible for President Donald Trump to deliver on his promise tocut corporate tax rates to 15%.

In separate appearances Tuesday, Treasury Secretary StevenMnuchin and Marc Short, Trump's legislative affairs director, bothsaid Trump is still committed to that rate cut—down from thecurrent 35%—but acknowledged the potential for compromise.

“The president has made it clear since the campaign, ideallyhe'd like to get it down to 15%. I don't know if we'll be able toachieve that given the budget issues, but we're going to get thisdown to a very competitive level,” Mnuchin said at CNBC'sDelivering Alpha conference in New York. “What the exact number isless important, what's important is making sure we have acompetitive system.”
