The presumptive presidential nominees for both major parties are reacting after a mass shooting overnight in an Orlando gay nightclub left 50 people dead and 53 injured — making it the deadliest mass shooting in the nation's recent history.

Democrat Hillary Clinton tweeted in both English and Spanish that she "woke up to hear the devastating news."

Republican Donald Trump also reacted on Twitter Sunday morning, calling the shooting "really bad."

Democrat Bernie Sanders, who remains in the race despite news last week that Clinton had secured enough delegates to become the party's nominee, called the news "unthinkable" on Meet the Press Sunday morning.

The White House released a statement saying that President Obama had been briefed on the situation and would be receiving regular updates.

"The President asked to receive regular updates as the FBI, and other federal officials, work with the Orlando Police to gather more information, and directed that the federal government provide any assistance necessary to pursue the investigation and support the community," the statement read.

NPR is reporting that the shooting suspect has been tentatively identified as Omar Mateen, citing two unnamed law enforcement officials. The suspect was killed in a gun battle with officers. No further information about the suspect was immediately available.
