共和党总统候选人特朗普也发文，称美国被激进的伊斯兰恐怖分子（radical Islamic terrorist）袭击。他还表示，奥巴马在讲话中没有使用Radical Islam这两个词，他就应该下台；希拉里如果也不敢说这两个词，她应该退出总统竞选。
特朗普声明全文：
Last night, our nation was attacked by a radical Islamic terrorist. It was the worst terrorist attack on our soil since 9/11, and the second of its kind in 6 months. My deepest sympathy and support goes out to the victims, the wounded, and their families.
In his remarks today, President Obama disgracefully refused to even say the words 'Radical Islam'. For that reason alone, he should step down. If Hillary Clinton, after this attack, still cannot say the two words 'Radical Islam' she should get out of this race for the Presidency.
If we do not get tough and smart real fast, we are not going to have a country anymore. Because our leaders are weak, I said this was going to happen – and it is only going to get worse. I am trying to save lives and prevent the next terrorist attack. We can't afford to be politically correct anymore.
The terrorist, Omar Mir Saddique Mateen, is the son of an immigrant from Afghanistan who openly published his support for the Afghanistani Taliban and even tried to run for President of Afghanistan. According to Pew, 99% of people in Afghanistan support oppressive Sharia Law.
We admit more than 100,000 lifetime migrants from the Middle East each year. Since 9/11, hundreds of migrants and their children have been implicated in terrorism in the United States.
Hillary Clinton wants to dramatically increase admissions from the Middle East, bringing in many hundreds of thousands during a first term – and we will have no way to screen them, pay for them, or prevent the second generation from radicalizing.
We need to protect all Americans, of all backgrounds and all beliefs, from Radical Islamic Terrorism - which has no place in an open and tolerant society. Radical Islam advocates hate for women, gays, Jews, Christians and all Americans. I am going to be a President for all Americans, and I am going to protect and defend all Americans. We are going to make America safe again and great again for everyone.
