Summary

Top Republican senators are calling for an investigation into the Signal leak scandal after senior Trump administration officials accidentally added a journalist to a chat discussing military strikes on Yemen.

National security adviser Mike Waltz took responsibility, but conflicting statements from Waltz and Trump have fueled confusion.

Republicans are urging probes by the Senate Armed Services and Intelligence Committees.

Tensions within the GOP are growing, with hawkish Republicans supporting Waltz and Trump loyalists opposing him. Legal challenges have also emerged over potential violations of the Federal Records Act.
