Marco Rubio was haunted tonight by his past issues in the Senate. The 'Gang of Eight' and his leisure to side with those who support mass government surveillance were two areas that he was hit on.
Ted Cruz took the first shot when he challenged Rubio's voting record on the Senate floor in regards to government surveillance and the lack of accountability shown in San Bernardino.
Rand Paul jumped in and questioned Rubio's membership in the 'Gang of Eight', which includes Senators like Bob Menendez and Chuck Schumer who support amnesty.
