"Every day that we fail to act on gun violence, we are failing our children," Clinton tweeted. "This should be a day for soul searching across America — and that soul searching should be matched with legislating to begin dealing with this national shame."

The former presidential candidate's tweet came hours after a gunman opened fire at Santa Fe High School near Houston, leaving at least 10 people dead and several others injured. 

A 17-year-old suspect has been taken into custody, and a person of interest has been detained, as well. Harris County Sheriff Ed Gonzalez said that both individuals are believed to be students at the school.

At the same time, police said that they had located possible explosive devices at the school and off campus, though no explosions have been reported.

“This has been going on too long in our country, too many years, too many decades now,” Trump said during a prison reform event at the White House, hours after the attack occurred.

“My administration is determined to do everything in our power to protect our students, secure our schools and to keep weapons out of the hands of those who pose a threat to themselves and to others,” he added.

The U.S. has grappled with whether to impose stricter gun laws since a mass shooting at Marjory Stoneman Douglas High School in Parkland, Fla., on Feb. 14 left 17 people dead.
