WASHINGTON (Reuters) - A 15 percent corporate tax rate backed by President Donald Trump may not be possible, but businesses will see a “competitive” rate as Republicans push their tax reform plan through Congress, the U.S. treasury secretary said on Tuesday. “Ideally, he’d like to get it down to 15 percent. I don’t know if we’ll be able to achieve that given the budget issues, but we’re going to get this down to a very competitive level,” Steven Mnuchin said, speaking at an conference hosted by CNBC.
