TAMPA - A member of Mitt Romney's Secret Service detail was removed today from a campaign trip after she accidentally left her firearm unattended in the candidate's charter plane bathroom. The agent in question left a gun unattended in the bathroom of the plane during a flight between Tampa and Indiana. The gun was found by a reporter on board who immediately informed the agent, who then went back into the bathroom and retrieved the weapon. Ed Donovan, a spokesman for the United States Secret Service, told ABC News that officials are "aware of the incident."
