At least 50 people were shot and killed at a Jason Aldean concert in Las Vegas late Sunday night, and another 406 were injured in what has become the deadliest shooting in modern U.S. history.
The gunman, 64-year-old local resident Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel toward the 22,000-person crowd at the Route 91 Harvest Festival. He was later found dead by officers.
President Donald Trump was among the first to react on Twitter Monday morning. "My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you," he tweeted.
