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.

President Trump attacked a GOP senator who voted with Democrats as a "pawn" and "second-tier" in a Truth Social post.

Investors braced for the Federal Reserve's next interest rate decision and earnings from tech giants Microsoft and Meta.

The Fed is seen as virtually certain to leave interest rates unchanged despite intense pressure from President Donald Trump and his allies on Chair Jerome Powell to deliver a cut.
