Sen. Frank R. Lautenberg (D-N.J.) underwent surgery to treat a head injury from a skiing accident a month ago. Lautenberg, 79, fell and hit his head while skiing in Aspen, Colo., a spokesman said. He had had a low-grade headache since then.
He checked himself into a New York hospital late Saturday. Doctors found blood had collected in an area inside the senator's skull that required surgery to drain. The spokesman said Lautenberg would need two days to recover.
