The Hill reports Sen. Craig Thomas (R-WY), who has battled leukemia in recent months, is in serious condition at National Naval Medical Center in Bethesda, Md., according to a statement released by his family. Craig is "undergoing a second round of chemotherapy, but his blood cancer has resisted treatment, and he is suffering from infection."

Roll Call adds that Thomas, 74, was "first hospitalized on May 24 following a round of routine blood tests to monitor his bone marrow and white and red blood cell counts" but the cancer has been resistant to recent efforts and he continues to struggle with infection and the leukemia, according to the family. "Thomas had been headed toward a remission earlier this year, and his doctors opted against a March treatment because of his positive response. Thomas had gotten back to his routine in the Senate, keeping to a regular vote and committee schedule."

In January Thomas said he "felt very good and very normal," adding that "when these things happen, you have to do what's necessary to deal with it."
