Donald Trump said President Obama seemed more outraged with him than with the Orlando gunman after the billionaire's comments regarding the tragedy.
After the gunman, who was Muslim, fatally shot 49 people and injured 53 others, Trump had renewed his call for a ban on Muslims entering the country.
On Tuesday, Obama responded: "We now have proposals from the presumptive Republican nominee for president of the United States to bar all Muslims from immigrating to America.
"We hear language that singles out immigrants and suggests entire religious communities are complicit in violence... Where does this stop?"
On Tuesday night, Trump fired back.
"I watched President Obama today, and he was more angry at me than he was at the shooter — and many people said that," he told an audience in Greensboro, North Carolina.
"One of the folks on television said, 'Boy, has Trump gotten under his skin.' And a lot of people have said this, that's the kind of anger he should have for the shooter and these killers that shouldn't be here."
On Thursday, Obama will travel to Florida to pay his respects to the victims of the nightclub shooting and "to stand in solidarity with the community as they embark on their recovery," the White House said.
