Sen. Marco Rubio (R-Fla.) blitzed all five Sunday shows in his most public pitch yet for the emerging immigration reform bill, arguing that it would control the border and rejecting conservative criticisms that it provided “amnesty” for illegal immigrants in the country.

“This is not ‘amnesty.’ ‘Amnesty’ is the forgiveness of something. ‘Amnesty’ is anything that says ‘do it illegally, it’ll be cheaper and easier,'” Rubio, a member of the bipartisan ‘Gang of Eight’ senators set to unveil their immigration bill on Tuesday, said on “Fox News Sunday.”

Rubio, a Tea Party favorite, is a key figure in winning GOP support for the bill overhauling the nation’s immigration laws through tighter border security and a pathway to citizenship for those illegal immigrants already in the country.
