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.

Sen. Rand Paul, R-Ky., urged Democrats to vote against the bill because it included an exemption for Trump and Vance. Sen. Bernie Moreno, R-Ohio, the original bill’s cosponsor, pulled his support when Hawley introduced the modified version, telling lawmakers during a hearing Wednesday “I have no idea what we’re voting for.”
