"We owe it to our children and our teachers to keep them safe while at school," Kardashian tweeted. "Prayers won't do this: action will. Congress, please do your job and protect Americans from senseless gun violence."

DeGeneres echoed those sentiments.

"No words, no actions, no laws are enough until we end this epidemic of school shootings in our country," she said. "My heart is with the students and parents of Marjory Stoneman Douglas High School."

As for President Trump, he added that nobody "should ever feel unsafe in an American school."

Authorities arrested suspect Nikolas Cruz miles away from the deadly school shooting. He had been expelled from the school and students who knew him said that he "always had guns on him."
