Arizona Senator Ruben Gallego faces sexual misconduct allegations after Rep. Anna Paulina Luna told CBS News a woman is coming forward with claims of "an event with a sexual nature." Luna confirmed an ethics investigation exists, triggering massive market swings on his potential exit from office. The scandal comes as Gallego has been actively working on Arizona housing issues and veterans' affairs in recent weeks, with his spokesperson dismissing the claims as "right-wing conspiracy theories." The September exit market collapsed from 81¢ to 16¢, while November odds fell to 18¢ from 60¢, as traders rapidly repriced the likelihood of a resignation amid what could become a Senate ethics committee investigation.
