A Democrat running for the U.S. Senate in Maine is withdrawing from the race. Graham Platner's decision comes after a sexual assault allegation was made against him. His campaign had been controversial for months before this development.

The impact of Platner's exit is still being assessed. Maine is an important state in the battle for control of the Senate, and Democrats had been hoping to win the seat currently held by a Republican.

Further details about the situation and its implications are available from KSAT 12, a local news source in San Antonio.
