After tweeting his response to the mass shooting that occurred in Orlando on Sunday, Donald Trump is now facing backlash. Trump "congratulated" himself on "being right" about terrorism on Twitter Sunday, after news of the mass shooting broke.

Senator John McCain's daughter Meghan McCain criticized Trump on Twitter. "You're congratulating yourself because fifty people are dead this morning in a horrific tragedy?" she said. GOP strategist Ana Navarro also spoke out about Trump's comments on Twitter, accusing him of being self-centered and always wanting to be at the center of attention.

Several prominent Democrats criticized Trump including musician John Legend, venture capitalist Chris Sacca and actor George Takei. Legend called Trump "a truly awful person" on Twitter and Takei said that "once again Trump has shown why he cannot lead us."

In an interview on CNN's New Day, Trump warned there were "thousands of people" in the United States with "hate in their heart" and criticized Muslim communities for not reporting "mad" men like the Orlando shooter to the police or the FBI.

The presumptive Republican nominee also rejected the idea of having new gun laws to stop terrorists from buying weapons. "If you had guns on the other side, you wouldn't have had the tragedy you had," Trump said. "If you had guns in that room, even if you had a number of people having it strapped to your ankle or strapped to their waist, where bullets could have flown in the other direction right at him, you wouldn't have had the same kind of a tragedy." Trump also accused Hilary Clinton and President Barack Obama of facilitating these sort of tragedies.

Clinton called Trump's rhetoric "very dangerous for our country" on Monday and also dismissed Trump's accusations that she's afraid to use the words "radical Islamic terrorism." "I have clearly said, whether you call it radical Jihadism or radical terrorism, I'm happy to say either. I think they mean the same thing," Clinton said. She has also called for new restrictions to make it harder for home-grown terrorists to get guns.
