Texas Attorney General Paxton calls for increased funding for school security programs

"Look, we just spent 40 billion on Ukraine to help protect another nation," Paxton began. "It seems like the least we could do is fund a police officer or at least a program, because obviously there are thousands and thousands of schools in this country.

"A program that trains people in the school so that when this does happen, because it will happen again, we know what's going to happen. So if we know what's going to happen, let's do everything we can to prevent it from turning into the situation we just had yesterday," he added.

On Tuesday, 18-year-old Salvador Ramos entered Robb Elementary School at around 11:30 am local time and began firing, killing 19 children and two adults before being killed himself by a Border Patrol agent.

In the wake of the shooting, numerous school districts across the country have tightened their school grounds security.

In Duval County, Florida, chief of the Duval County School Police Department Greg Burton n notified families that there will be heightened security on school grounds, saying that the move was made out of an abundance of caution, according to News 4 Jax.

Clay County, and St Johns County, both in Florida, also issued similar messages to parents.

New Jersey Gov. Phil Murphy said on Wednesday that the New Jersey Office of the Attorney General had directed law enforcement to increase their presence at schools across the state.

In schools around the Washington DC area, the security has also been increased.

In DC itself Public Schools Chancellor Lewis D. Ferebee said that the system would "continue to work closely" with the DC police and other city agencies on school security, according to The Washington Post.

In Loudoun County, Virginia, the Sheriff’s Office has pledged to increase security at county schools to ensure that "our community feels safe in the schools."

In these communities, local officials and authorities have noted that there have been no credible threats, but that the action has been taken out of an abundance of caution.
