U.S. Rep. Danny Davis said his office received an e-mail threat on Sunday.

"It was some person who emailed one of my staff persons and said that 'Danny Davis is next,'" Davis said. Davis, a Chicago Democrat, said the Capitol Police and Chicago police have been notified.

Chicago police news affairs could not immediately confirm that a report of a threat had been filed with the department.

A spokeswoman with the Capitol Police did not immediately respond to a call and an e-mail tonight.

Davis said he would typically ignore such a threat, but a shooting Saturday that injured U.S. Rep. Gabrielle Giffords, killed six and injured 14, prompted him to be on alert.

"You know some things are cranks, some things are pranks. Some things you simply don't know about, but I think in this climate it pays to be as cautionary as one can be," he said.

Davis said the e-mailer is someone from Chicago who "operates around and in the community" and has been known to "do this before."
