Gingrich's speech focuses on the threat of radical Islam and national security. At the end he mentions what Trump plans to do regarding veterans' health care, infrastructure, education, and law and order.
After mentioning several attacks in the past month -- mass shootings and attacks around the world -- Gingrich says we have nothing to fear from the vast majority of the Muslims in the United States. The vast majority are peaceful, he says. "They are people we would be happy to be friends and neighbors with."
