Presumptive Republican presidential nominee Donald Trump will deliver remarks on terrorism just one day after the worst mass shooting in U.S. history.
In the wake of the attacks, Trump has been highly critical of American leaders including President Obama and presumptive Democratic nominee Hillary Clinton.
Trump has also re-upped calls to ban Muslims from immigrating to the U.S., because of the religion of the shooter, identified by police as Omar Mateen. Mateen, however, was an American-born U.S. citizen.
Mateen opened fire in an Orlando nightclub on Sunday, in a mass shooting that left 49 dead and 53 wounded. Mateen was killed in a shoot-out with police.
Officials believe the gunman was radicalized via the internet, but do not believe that he was directed by external terror groups.
Both Trump and Clinton will address the shooting in speeches on Monday. Trump will speak at 2:30 p.m. ET.
