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.

The bill passed the committee with the support of every Democrat and only one Republican, its sponsor, who modified it to shield President Trump from a divestment requirement.

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.
