Sen. Mark Udall's brother missing in Wyoming

The senator "has remained in contact with those searching for his brother and, along with his family, has waited and hoped for the best," spokesman James Owens said. "Nonetheless, he knows he still has a duty to lead — even with his brother missing — and has continued to serve while closely following the search."

Randy is also the first cousin of Sen Tom Udall (D-N.M.).
