Wall Street hits record high as Trump promises tax plan soon

Wall Street's three main indexes hit record intraday highs on Thursday after President Donald Trump said he would make a "phenomenal" tax announcement over the next two or three weeks. A post-election rally has sent Wall Street's indexes to record highs on bets that Trump would usher in an era of tax cuts, simpler regulations and higher infrastructure spending. "Lowering the overall tax burden on American business is big league," Trump said in a meeting with airline executives.
