Republican presidential hopeful Chris Christie on Thursday said primary rival Marco RubioMarco Antonio RubioColbert: Students taking action on gun violence 'give me hope' Lawmakers feel pressure on guns Florida lawmaker's aide fired after claiming shooting survivors were 'actors' MORE’s stance on abortion is too extreme for New Hampshire. 

The New Jersey governor said Rubio’s position against exceptions in the cases of rape, incest and threat to the life of the mother should give voters in the Feb. 9 primary cause for concern.

“I will tell you one thing Marco Rubio has done, he has made it very clear that on the issue of pro-life, Marco Rubio is not for an exception for ... rape, incest or life of the mother,” Christie said on MSNBC’s “Morning Joe."

“Now, you know, I think that’s the kind of position that New Hampshire voters would be really concerned about,” he added.

“I’m pro-life, but I believe that rape, incest and life of the mother — as Ronald Reagan did — should be exceptions to that rule." 

Christie, who has been increasing his attacks since the Florida senator's strong third-place finish in the Iowa caucuses, said Rubio’s abortion stance is evidence that he “moves and shifts depending on what he thinks he can get out of the electorate and what he can get from them.”

Rubio has previously attacked Christie for donating money to Planned Parenthood.
