Sen. Edward M. Kennedy returned to the senate on Wednesday, to cast his vote on an important Medical Bill, while he was being treated for cancer. He traveled all the way to Washington, to cast a vote in favor of the Medical Bill, which will block a 10 percent cut in Medicare payments to doctors because of a statutory formula that reduces payments to doctors.

Mr. Kennedy is the chairman of the Health, Education, Labor and Pensions Committee and is one of the 69 senators to vote in favor of the Bill. The Bill has now a veto-proof majority in both houses.

On the other hand, President Bush has threatened to veto the bill, as it would reduce payments to private Medicare Advantage plans offered by Human, UnitedHealth and Blue Cross and Blue Shield companies. But the veto will be overridden if the senate voted again as it did on Wednesday.
