President Barack Obama addressed the nation about the deadly shooting in Orlando Sunday afternoon.

President Obama talked to Orlando Mayor Buddy Dyer and said that whatever resources the city needed would be made available from the federal government.

During his address, Obama praised the work and responsiveness of law enforcement during the terrible attack.  The president, once again, touched on U.S. gun laws, saying today's shooting was a reminder of how easy it is for some people to get a gun.

The Office of the Press Secretary also released a proclamation from the White House, ordering all flags flown at half-staff until June 16 for victims of the shooting.

While the investigation was taking shape, the apparent Democratic and Republican presidential candidates swiftly responded to the shooting online.  

Both Hillary Clinton and Donald Trump offered prayers to the victims. Trump then pivoted, tweeting to his followers, quote: 

Trump later reiterated his position on banning Muslims from entering the country.

In reaction to the shooting, Hillary Clinton and President Obama postponed their first joint campaign appearance, which was scheduled for Wednesday. And Clinton on Twitter called for tougher gun control laws.

A sentiment President Obama echoed.

“This massacre is therefore a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school, or in a house of worship, or a movie theater, or in a nightclub," he said. "And we have to decide if that’s the kind of country we want to be."
