US midterms: Trump faces key test as voters decide Congress

Voting is underway Tuesday in the U.S. midterm elections, determining whether President Trump gains two more years of unified Republican rule or faces a Democratic check on his power, in the clearest national test of his second presidency. The Justice Department has sent target letters in an investigation into the Alaska Senate race, where Democrats allegedly recruited a candidate sharing Sen. Dan Sullivan's name. Republicans brace for potential losses in both chambers, with Trump campaigning heavily and making himself the election's central figure despite low polling. All 435 House seats and 35 Senate seats are contested, with Democrats needing net gains of three and four seats respectively to flip each chamber. Results will test Trump's 2024 voter coalition gains, while voting machine glitches and legal challenges could delay a clear verdict.
