Cruz: I stood with Jeff Sessions while Rubio led Dems' push for amnesty

Texas Sen. Ted Cruz let loose a new line of attack on Republican rival Marco Rubio on Friday. Cruz argued that while he sided with Alabama Sen. Jeff Sessions against amnesty, Rubio led the Democrats' fight against conservatives.

The GOP presidential candidates have publicly squabbled over their positions on the 2013 comprehensive immigration reform bill that passed the Senate in 2013. "Gang of Eight" bipartisan senators authored the legislation, including Rubio.

Cruz chastised Rubio in remarks to reporters after unveiling his own immigration reform plan on Rubio's home turf in Florida.

"[I]n the Gang of eight fight, Marco chose to stand with Chuck Schumer and to lead the fight tooth-and-nail for a massive amnesty plan," Cruz said. "I chose to stand with Jeff Sessions and to lead the fight to defeat amnesty. And we were successful in defeating it in the Congress."

Cruz avoided directly answering what he thought should be done about illegal immigrants already residing in the United States, but noted that he does not believe in comprehensive reform. His plan also seeks to increase the level of deportations.
