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.
