Sen. Edward Kennedy (D-Mass.) has left the hospital one day after he was diagnosed with a malignant brain tumor. No word yet on when Kennedy will return to the Senate.

Kennedy was headed to his home in Hyannis Port, Mass.

“Senator Kennedy has recovered remarkably quickly from his Monday procedure and therefore will be released from the hospital today ahead of schedule,” said Kennedy’s doctors in a statement. “He will return to his home on Cape Cod while we await further test results and determine treatment plans.

“He’s feeling well and eager to get started.”

President Bush paid homage to Kennedy Wednesday during the signing of the genetic nondiscrimination act, which Kennedy helped enact. The bill would prohibit employers or insurance companies from discriminating on the basis of genetic information.

“Our thoughts and prayers are with him and his family,” Bush said.
