In interviews and tweets during and after the shooting at a high school in Florida on Wednesday students and teachers that experienced the frightful event firsthand called on Congress to enact stricter gun control laws to prevent it from happening again.
"I want you to know that you are never alone and you never will be", Trump said.
"The FBI's failure to take action against this killer is unacceptable", Scott, a Republican, said in a statement. It's our own fault that we make weapons of mass death available in the marketplace.
With anger over the latest shooting still high, it would be naive to believe that gun control measures were poised for swift passage in state legislatures or, even more unlikely, in the U.S. Congress.
Many stars took to social media to express their sadness over the tragedy, which wounded at least 14 people.
Cruz was brought before a judge via video conference on Thursday at the Broward County court on 17 counts of premeditated murder after allegedly entering into Marjory Stoneman Douglas High School with a semiautomatic rifle where he began firing randomly at students and teachers on campus.
One Stoneman Douglas student who had attempted to flee rather than go on "lockdown" said he saw Cruz among the students as they ran out.
Students huddled in horror in their classrooms, with some of them training their mobile phones on the carnage, capturing sprawled bodies, screams and gunfire that began with a few shots and then continued. "I have two kids, and I think the only way it's going to stop is if we get the gun lobbyists off the back of politicians", Barry said. It was not a low-profile location for hiding out, and would likely have been one of the first establishments he came across as he moved west out of the school. Roger died of a heart attack in 2005. Following a disciplinary incident, Cruz was not allowed to carry a backpack to school and had to keep all his belongings in a transparent Ziploc bag, according to the Broward County Sheriff, Scott Israel.
During a press briefing on Thursday where authorities in Florida addressed the mass shooting at another American school, officials said that GoFundMe is a safe place to donate to help victims - and donors jumped at the chance.
President Trump tweets on Florida school shooting suspect: "Neighbors and classmates knew he was a big problem". "Must always report such instances to authorities, again and again".
Broward County's chief public defender, Howard Finkelstein, was quoted by the South Florida Sun Sentinel newspaper as saying Cruz's legal team planned to meet with prosecutors to offer a guilty plea in exchange for a life prison term.
