Gov. Chris Christie (R-N.J.) called presidential hopeful candidate Newt Gingrich an ?embarrassment? to the Republican party on ?Meet The Press? this weekend.

Now, former Alaska Gov. Sarah Palin is taking aim at Christie.

?You know sometimes when your candidate loses a step along the way as was the case with Mitt Romney's loss to Newt the other night, you kind of get your panties in a wad and may say things you regret later,? she said. ?And I think that's what Chris did here.?

Sarah Palin has not officially endorsed a candidate yet.
