Press Aide Arrested

A key House Republican says the arrest of a Department of Homeland Security official on sex-related charges raises serious concerns.

DHS spokesman Brian Doyle is accused of having sexually graphic conversations online with an undercover officer he thought was a 14 year old girl.

House Homeland Security Committee Chairman Peter King is questioning the department's hiring practices and security clearance practices.

King says Doyle may have used his government-issued computer to provide "potentially sensitive information" to a stranger.

King says that person could have been a member of al-Qaida who could have used the information to blackmail Doyle.

Authorities say Doyle revealed his name and his employer and offered the numbers of his Homeland Security-issued office and cell phones during the online conversations.

Doyle's attorney says his client had lost a brother and a sister in separate incidents several years ago around March or April and that could have triggered depression at this time of year.
