U.S. President Donald Trump on Thursday ignored a question by a reporter during a White House briefing who asked if he regretted all the lying he has done while in office. "Mr. President, after three and a half years, do you regret at all, all the lying you've done to the American people?" asked Shirish Date, Huffington Post's White House correspondent, who later tweeted that he had waited for five years to ask him that question.
