Now State Senator Sam McCann has declared himself a third party candidate for Governor, a Republican colleague in the General Assembly is calling for McCann to call it a day in the legislature.. State Representative Tim Butler of Springfield says resigning is the right thing to do.

Butler says McCann has betrayed the party and the party's voters.

McCann's status as a member of the Republican caucus is up in the air. 
Senate GOP officials say McCann tendered his resignation from the Illinois Senate Republican caucus and Leader Bill Brady accepted. McCann says he only resigned his position as the top Republican on the Senate Public Health Committee.
