Missouri Republican Sen. Josh Hawley voted with Democrats Wednesday to advance his bill to ban US lawmakers from stock trading, over the opposition of other Republicans on the panel and drawing the ire of President Donald Trump.

Josh Hawley is brushing off President Donald Trump’s quip that he’s a “second-tier” senator. The criticism came after the Missouri Republican’s proposal to ban stock trading by members of Congress — and the president and vice president — won bipartisan approval to advance in a committee vote.
