"My heart goes out to the victims of this senseless violence, to their loved ones, and to all those affected."

Whitehouse also thanked the first responders for their brave work.

"While we have much to learn about this terrible incident, we know mass shootings are all too familiar in America," he said.

"And we know we can protect our communities better. How many lives must be lost before we act?"

At least 50 people were killed and hundreds more injured when a gunman opened fire at a country music festival in Las Vegas Sunday night.

Other lawmakers have since called for Congress to act on gun violence in the wake of the Las Vegas mass shooting, the deadliest U.S. history.

President Trump extended his sympathies to the victims of the attack earlier Monday and has been briefed on the shooting.
