President Donald Trump described the current US tax code as “a self-inflicted economic wound” while promoting the Republican tax plan before an audience of supporters in St. Charles, Missouri on Wednesday. The plan would cost him personally “a fortune, believe me,” he said, without offering details. The White House has said the plan will benefit middle-class families and spark economic growth by helping small business owners and workers. Critics say the House and Senate versions both disproportionately help corporations and the wealthy. The Missouri speech was part of a push for the tax cut package, ahead of an expected Senate vote later this week.
