President Trump condemned a shooting Sunday evening in Las Vegas that claimed 50 lives as "an act of pure evil," and said he would visit the city on Wednesday to meet with first responders from the attack.

"We are joined together today in sadness, shock and grief," Trump said during his first public remarks on the shooting Monday.

"In moments of tragedy and harm, America comes together as one, and it always has," he said. "We call upon the bonds that unite us: of faith, of family, and our shared values."

"Though we feel such great anger at the senseless murder of our fellow citizens, it is our love that defines us today," he added.

Trump commended the first responders for acting quickly to locate and neutralize the shooter Sunday evening and for tending to the dozens of victims who were left dead and wounded after the attack.

"I want to thank the Las Vegas Metropolitan Police Department and all of the first responders for their courageous efforts and for helping to save the lives of so many. The speed with which they acted was miraculous and prevented further loss of life," Trump said.

The president also offered words of comfort for family members of the more than 50 people who died in the shooting.

"We cannot fathom their pain, we cannot imagine their loss. To the families of the victims, we are praying for you and we are here for you and we ask God to help see you through this very dark period," Trump said.

Trump rearranged his schedule Monday in response to the shooting by pulling out of a deregulation event and adding the speech in the Diplomatic Room.

More than 50 people were killed and more than 400 injured Sunday evening when a gunman opened fire on a crowd of concertgoers on the Las Vegas strip.

Stephen Paddock, the 64-year-old suspected shooter, killed himself before police entered his room in the Mandalay Bay hotel. Paddock had numerous guns with him in his room on the 32nd floor of the hotel, where he rained gunfire down on the audience of a country music festival.

The Islamic State claimed credit for the attack on Monday, although authorities have not provided any evidence to support that link.

Quinn Averett, an officer with the Mesquite Police Department, said officers searched Paddock's home in Mesquite, Nev., on Monday and discovered an unspecified number of guns and ammunition. Averett said agents are interviewing the suspect's neighbors.
