White House press secretary Sarah Huckabee Sanders  choked up on Monday while reading a statement about the mass shooting in Las Vegas  Nevada.
"What these people did for each other says far more about who we are as Americans than the cowardly acts of a killer ever could "  Sanders  said during the White House daily press briefing.
 Sanders  faced questions during the briefing with reporters on potential policy responses to the shooting.
Though President Donald Trump is oftentimes known for his willingness to wade into politics during tragedies related to terrorism   Sanders  said the White House hoped to avoid politicizing the tragedy  saying there's "a time and place for a political debate."
 The press secretary  cautioned against taking policy steps to curb mass shootings by enacting gun control legislation.
"There will be certainly time for that policy discussion to take place  but that's not the place that we're in "  Sanders  said.
