Washington ? Sen. Edward M. Kennedy was released from the hospital and doing well Wednesday after suffering a seizure during an inaugural luncheon.

Kennedy’s office confirmed that the senator left Washington Hospital Center, where he stayed overnight for observation, and was resting at home. Kennedy has been under treatment for a brain tumor since last spring.

A Kennedy representative, who spoke on condition of anonymity because the announcement was not official, said the senator was in good spirits and that doctors wanted him to get some rest.

Doctors blamed fatigue for the seizure Kennedy suffered during the Capitol Hill luncheon Tuesday after attending the swearing-in of President Barack Obama.
