Rep. Jim Matheson, D-Utah, said in a statement, "I am disturbed by what has been reported so far. I assume the matter will be thoroughly investigated by authorities."
Sen. Bob Bennett, R-Utah, who along with Craig was a Senate liaison for presidential candidate Mitt Romney's campaign, said the news on Craig is a blow to Republicans' political fortunes, but it is also personally difficult. He said he and his wife, Joyce, are close friends with the Craigs, and Joyce has been "sickened" by the events.
Craig resigned from the Romney campaign and the organization scrubbed its Web site of references to Craig's involvement.
Rep. Rob Bishop, R-Utah, declined comment. Rep. Chris Cannon, R-Utah, was in Kazakhstan and unavailable for comment, as did Sen. Orrin Hatch, R-Utah, who was celebrating his 50th wedding anniversary.
