WASHINGTON (CNN) - Sen. Craig Thomas, R-Wyoming, is in serious condition after undergoing a second round of chemotherapy treatment for leukemia, his family said in a statement Monday.
"At this difficult time, all we can do is give him as much love and support as possible," his wife Susan said in a statement. "The support and prayers of Wyoming folks have made a tremendous difference to us. It has meant everything to Craig, and I know it helps him today."
Doctors said Thomas is struggling with an infection, and his body has been resistant to the treatment, according to the statement.
Thomas is being treated at the National Naval Medical Center in Bethesda, Maryland. He is with his wife, sons Patrick and Greg and daughter Lexie. "The family wants to thank everyone for their positive wishes and prayers," they said in the statement.
