Senate Majority Leader Harry Reid (D-Nev.) is backtracking on comments that he made Tuesday that Sen. Edward Kennedy’s (D-Mass.) brain cancer is in remission.”Senator Reid will leave the diagnosing to doctors,— Reid spokesman Jim Manley said in a statement clarifying Reid’s earlier comments. “But he does look forward to the prospect of Senator Kennedy’s return to the Senate as soon as he is able.”On Tuesday, when asked by reporters whether Kennedy’s cancer was in remission, Reid said: “As far as I know, yeah.—“I had a conversation with Mrs. Kennedy in the last couple of days. He’s doing fine,— Reid said, adding that Kennedy was receiving “another regimen of treatment, which is not unusual.—Kennedy, 77, was diagnosed with brain cancer last year and has spent much of that time recovering and receiving treatment. Kennedy is currently in Massachusetts and is said to be continuing to balance treatment with his Senate duties. Reid also suggested Tuesday that Kennedy may be back at work after the Memorial Day recess. But sources close to the Senator maintain that no timeline has been set for his return.
