(CNN) – Sarah Palin is getting more advice from fellow Republicans – this time from former House Speaker Newt Gingrich who says the former Alaska governor needs to "slow down."
Speaking on ABC's Good Morning America Tuesday, Gingrich said a string of Palin's recent statements indicate she needs to "be more careful and think through what she's saying and how she's saying it."
"There's no question that she has become more controversial," added Gingrich who may face off against Palin later in the year for the GOP presidential nomination.
But Gingrich was quick to add he believes Palin remains a "phenomenon and "very formidable in her own right."
Gingrich's comments come in the wake of Palin's controversial handling of the Arizona shootings, after which she accused members of the media and left-wing critics of engaging in a "blood libel" against her. Speaking on Fox News Monday, Palin said she meant the term to mean she was the victim of false accusations of being an accessory to the killings.
Gingrich's comments also follow those of New Jersey Gov. Chris Christie, a Republican favorite who told the New York Times Palin needs to engage with the media and voters in settings less staged than those she currently utilizes.
As for his own political future, Gingrich reiterated he will make an announcement about his potential presidential campaign in late February.
