President Donald Trump is skipping his planned interview with Fox News anchor Sean Hannity scheduled for this Wednesday in order to travel to the scene of the deadly mass shooting in Las Vegas, Fox News announced Monday.

The interview was to take place in front of a group of Republicans, Democrats, and Independents at the Morgantown Theatre in West Virginia. Hannity and Trump were set to discuss tax reform, the economy, and news of the day, and there was to be time allocated for a Q&A session with the audience at the end of the interview. According to a statement from a Fox News spokesperson, the network is looking into rescheduling the interview.

On Sunday night, a man opened fire from his room on the 32nd floor of the Mandalay Bay Hotel and Casino on the Vegas Strip with a high-powered assault rifle, targeting the Route 91 Harvest Music Festival nearby. At least 58 people have died and more than 500 were injured in what is now the deadliest mass shooting in U.S. history. Police subsequently identified 64-year old Stephen Paddock, a resident of nearby Mesquite, Nevada, as the shooter. S.W.A.T. officers breached Paddock’s room with explosives, though he appears to have killed himself before police entered the room. Police also said that at least 10 weapons were found in Paddock’s possession.

FBI agent Aaron Rouse, who oversees Las Vegas for the bureau, dismissed a claim by the Islamic State terror group that Paddock was one of its operatives. “We have determined to this point no connection with an international terrorist group,” Rouse said. “We will continue to work with our partners to ensure that this is factually, thoroughly and absolutely investigated.”

The shooting broke out at the end of a Jason Aldean set, with some witnesses reporting that they had heard possibly hundreds of shots and saw at least one officer down. Videos posted to Twitter show concertgoers sheltering in place as gunshots are heard ringing throughout the area.
