White House press secretary tears up while talking about Las Vegas victims

White House Press Secretary Sarah Huckabee Sanders became emotional as she spoke about the victims of last night's deadly shooting in Las Vegas, Nevada.

"What these people did for each other says far more of who we are as Americans than the cowardly acts of a killer ever could."

At least 58 people have died and hundreds injured in what is now the deadliest mass shooting in modern U.S. history.
