The US Senate rejected the Stop Insider Trading Act, which would have prohibited members of Congress from trading stocks, in a 53-47 vote that prevented it from reaching President Trump's desk. Although the bill had already passed the House with some Democratic support, Senate Republicans attached voter identification requirements that Democrats denounced as a "poison pill," contributing to its defeat. The failure means lawmakers will continue to be permitted to trade stocks whilst possessing non-public information, a practice critics view as a significant conflict of interest.

The measure was sponsored by Nebraska Republican Pete Ricketts, with support from colleagues including Missouri's Josh Hawley, though some backers acknowledged it lacked sufficient scope. West Virginia Republican Jim Justice criticised the timing, arguing voters would perceive it as political opportunism—a "too little, too late" gesture made just before the November midterms, potentially reversible after elections. Under current regulations, US lawmakers may trade stocks but must disclose transactions only after execution; efforts to impose such a ban have been debated throughout the 119th Congress over the past two years.
