Donald Trump refers Orlando shooter Mateen as 'son of a b***h'

Presumptive GOP presidential candidate Donald Trump has referred to the Orlando terrorist attack gunman as a "son of a bitch", arguing that guns in civilian hands could have mitigated the carnage.

"If we had people, where the bullets were going in the opposite direction, right smack between the eyes of this maniac. And this 'son of a bitch' comes out and starts shooting and one of the people in that room happened to have (a gun) and goes boom. You know what, that would have been a beautiful, beautiful sight, folks," CNN quoted him as saying.

Speaking to his supporters yesterday, he argued that fewer gun restrictions would have lessened the death toll.

The New York billionaire also slammed US President Barack Obama for arguing for action to change in existing gun laws in the wake of the mass shooting in Orlando.

"President Obama is trying to make terrorism into guns and it's not guns, folks. It is not guns, folks. It is not guns, this is terrorism," he said.

His remarks comes days after he himself called the idea of preventing individuals on the no-fly list and terror watch list from being able to purchase guns, a proposal Obama and top Democrats have pitched for following the Orlando attack.

Fifty people were killed and fifty-three others injured after 29-year-old Omar Mateen opened fire inside a gay nightclub in Orlando on June 12.

He was killed by the Orlando Police after a three-hour standoff.

The mass shooting is considered to be the deadliest one by a single gunman against the LGBT people in U.S. history, and also the deadliest terrorist attack since the September 11 attacks in 2001.
