(CNN) - New York City Mayor-elect Bill de Blasio was with President Barack Obama in a meeting on Friday when the President received a note about a school shooting in Colorado.
"Well, the President said very somberly that the shooting had occurred. Obviously none of us had the details yet, but he informed the room - the note was passed to him and he informed the room immediately and we all cringed," the Democrat told reporters at the White House.
A student opened fire Friday inside a suburban Denver high school, injuring at least two people before turning the gun on himself, authorities said.
De Blasio was part of a group of newly elected mayors meeting with Obama at the White House to talk about jobs. But after hearing news about the school shooting, the mayor-elect said the conversation pivoted to a discussion about gun control.
"We didn't get into a lengthy conversation but the immediate comment from some of the mayors in the room was: How can we use our abilities, how can we use our local capacity and our bully pulpits to try and move forward sensible gun control legislation? Because until we do that there's too many dangers out there. That's what people were focusing on," he said.
De Blasio will succeed three-term Mayor Michael Bloomberg.
