During a 2013 interview with Fox News, the real estate mogul defined himself as, a very strong person on the Second Amendment. He believes guns are necessary for self-defense and has written that he generally opposes gun control. In his 2000 book, The America We Deserve Trump wrote that he supports a ban on assault weapons and a slightly longer waiting period to buy a gun.
