With Afghanistan hearings Tuesday and the annual Pentagon budget bill due on the House floor this week, a familiar face may be missing. Rep. John Murtha, chairman of the House Appropriations defense panel, was hospitalized Sunday night because of abdominal pains. The 77-year old Pennsylvania Democrat had been feeling ill with what he thought last week was swine flu but the hospitalization appears related to his gall bladder. “He’s currently resting and doing well,” his office said.
