White House press secretary Sarah Huckabee Sanders says the day after the deadliest mass shooting in the nation’s history is not the time to renew a debate over gun control.

She said President Donald Trump was focused on the victims and stressed that it was a “time to unite the country.”

Democratic Sen. Chris Murphy of Connecticut says it’s time for Congress to do something about mass shootings after more than 50 people were gunned down in Las Vegas.

Murphy, a leading gun-control proponent, said mass shootings had become an “epidemic” in America.

Other Democrats condemned the shooting but did not specifically urge gun-control legislation. Action in the Republican-controlled Congress is unlikely.
