Just hours after the president used the veto pen to scrap the Medicare bill, the Senate will move Tuesday evening to override that action.

Majority Leader Harry Reid (D-Nev.) said that the Senate will hold a vote around 5:30 p.m. on the House-crafted Medicare bill that passed just one week ago.

Late last week, Reid said that he expected all18 Republicans who joined the Democrats in approving the bill to maintain their support for it in an override vote.

Sen. Edward Kennedy (D-Mass.), who is undergoing treatment for a malignant brain tumor, helped provide the critical margin with a surprise return to the chamber last week, but Kennedy was not slated to come back for the override vote.

Reid, however, said that it is unlikely that he will need Kennedy’s vote since many GOP lawmakers have indicated to him that they plan to vote for the Medicare bill.
