WASHINGTON, Dec 13 (Reuters) - President Donald Trump said on Wednesday he would accept a corporate tax rate of 21 percent and would sign a bill with that number. The White House has previously said it preferred a 20 percent tax rate for corporations, down from 35 percent at current levels. “If it got down to 21 ... I would be thrilled,” he said. “We haven’t set that final figure yet.” (Reporting by Jeff Mason; Editing by James Dalgleish)
