Chris Matthews Slams Arizona State Rep: 'BS Artist' (VIDEO)

Chris Matthews went head-to-head over immigration reform with Republican Arizona State Representative Rick Murphy on "Hardball" Wednesday night — and things got heated.

Matthews dubbed Murphy "one of the BS artists of the world" for his opposition to a national ID card to facilitate legal employment.

Matthews later said Murphy was "not serious" about finding a solution to the immigration problem. Murphy shot back, accusing Matthews of setting up "a straw man where if I don't agree with your position, then I don't want a solution."

'You are a hopeless right-winger," Matthews responded.
