WASHINGTON — Senators are preparing to challenge military leaders over President Donald Trump’s controversial use of the National Guard in American cities, prompting significant legal and ethical debates. The Senate Armed Services Committee's hearing aims to investigate the legality and implications of these deployments, which have occurred despite objections from local officials. This scrutiny is critical, especially after a federal judge recently ruled against Trump's deployment plans in California. Senator Tammy Duckworth highlights concerns about the guard's impact on military readiness and the safety of service members amid these politically charged operations.
