(CNN) - Sen. Ted Kennedy, who was diagnosed with a cancerous brain tumor nearly two months ago, is weighing whether to return to the Capitol Wednesday afternoon, for the first time since he got sick, to help break a Republican filibuster of an important Medicare bill, a senior Democrat on Capitol Hill told CNN.
The source said Kennedy’s return has been “discussed but is doubtful” because Kennedy’s family is concerned the travel would be too strenuous on the 76 year-old who had surgery to remove the tumor and is now undergoing chemotherapy and radiation treatment.
The vote is scheduled for 4 p.m. so a final decision is expected shortly whether to have Kennedy leave Massachusetts and fly to Washington.
Senate Majority Leader Harry Reid has talked to Kennedy’s wife Vicki twice since Sunday about having Kennedy return for the vote, the source said. Reid “was not pushing, just asking,” the source said.
“The family doesn’t want to do it,” the source said.
A previous vote fell one vote shy of clearing the filibuster just over a week ago. The underlying bill would reverse a 10.6 percent cut in Medicare payments to doctors that will go into effect this month.
Kennedy is chairman of the Health, Education, Labor and Pensions Committee and is an influential Democrat on health care issues. Some members of the Democratic leadership think it would be a “great idea” if Kennedy were able to return because it would “buck up” Democratic senators who have worked hard to pass the stalled bill, the source said.
