Earlier President Obama branded the attack on the LGBT community as "an attack against us all."

"The shooter targeted a nightclub where people came together to be with friends, to dance, and to sing, and to live. That place where they were attacked was more than a nightclub. It's a place of solidarity and empowerment where people have come together to raise awareness, to speak their minds and to advocate for their civil rights," the president said.

He continued: "This is a sobering reminder that attacks on any American, regardless of race, ethnicity, religion or sexual orientation, is an attack on all of us and on the fundamental values of equality and dignity that define us as a country. And no act of hate or terror will ever change who we are or the values that make us Americans."

As the entertainment world shows its solidarity for the LGBT community and unites to condemn terrorism, it has been announced that The Tony Awards will be dedicated to the people of Orlando as they come to terms with the deadliest mass shooting in US history.

"Our hearts are heavy for the unimaginable tragedy that happened last night in Orlando," the Tonys producers said in a statement. "The Tony Awards dedicate tonight's ceremony to them."

The Tonys, taking place at Manhattan's Beacon Theater, will be hosted by James Corden of CBS's "Late Late Show.".

The Broadway smash musical "Hamilton", which earned a record 16 Tony nominations has announced they will not use of muskets in its performance at the Tony Awards on Sunday night, in the wake of the shooting.
