SIOUX CITY, Iowa (AP) — Newt Gingrich says he's trying to edit himself so he doesn't come across as "zany."
Gingrich's remarks at the Republican debate Thursday night were aimed at rival Mitt Romney, who in an interview on Wednesday used the word "zany" to describe the former House speaker.
Gingrich smiled when he was asked a question about how he would counsel Republicans on the political controversy over construction of a new pipeline from Canada to the Gulf of Mexico.
Gingrich said that at times he is accused of using language that is too strong and so he was "editing" himself. He then quipped that he's very concerned about not appearing to be "zany."
Romney has stepped up attacks on Gingrich's temperament as Gingrich has vaulted to the top of the GOP field.
