Senator Ted Cruz really got lit up during Bret Baier's interview with him on Tuesday, which exposed him as a flip flopper on immigration and opened him up to the kind of attacks Marco Rubio is facing, as the amnesty in chief presidential candidate.

Napolitano: You performed a classic cross examination on one of the finest debaters in America, Senator Cruz, and he really couldn't answer your question because you impeached his credibility.

When the judge calls a Republican a liar on Fox News, that's kind of big, even for tea party darling, Ted Cruz.

What was Cruz' response to his debacle on Fox News?

Sen. Ted Cruz (R-TX) is air­ing a new TV ad in Iowa about his op­pos­i­tion to am­nesty. In the spot, Cruz slams Pres­id­ent Obama’s im­mig­ra­tion plan, claim­ing “it would have giv­en Obama the au­thor­ity to ad­mit Syr­i­an refugees, in­clud­ing IS­IS ter­ror­ists.”

Cruz also “rat­cheted up his at­tack on” Sen. Marco Ru­bio (R-FL) “on Thursday by in­sinu­at­ing that … Ru­bio had broken his prom­ise to voters who elec­ted him to fight ‘am­nesty’ for un­doc­u­mented im­mig­rants.” Cruz is “al­lud­ing to … Ru­bio’s spon­sor­ship of a 2013 bill that would have giv­en people in the coun­try il­leg­ally a path­way to cit­izen­ship.”
