In a proclamation honouring the victims of the school shooting, Biden has ordered that the flag of the United States shall be flown at half-staff at the White House and upon all public buildings and grounds and at all military posts and naval stations until sunset, May 28, 2022.
The US flag will also be at half-mast across all embassies, consular offices and military facilities.
The school shooting has once again stoked the fiery debate on gun control. Texas Attorney General Ken Paxton has suggested arming the teachers to prevent such incidents in the future.
Speaking to a media outlet, Paxton said: "First responders typically can't get there in time to prevent a shooting. It's just not possible unless you have a police officer on every campus. I think you're going to have to do more at the school."
US Senator John Cornyn (Republican-Texas) said in a tweet: "Today, the entire state of Texas is in mourning. The shooting at Robb Elementary School is every parent and teacher's worst nightmare. My heart goes out to those in the hospital receiving care and to the loved ones of those who lost their lives. As a parent, I cannot imagine the pain they must be feeling."
"I am in touch with local officials in Uvalde and plan to travel there as soon as I can get there. No parent, child, or teacher should ever have to wonder whether it's safe to go to school. This is an excruciatingly painful time for the tight-knit Uvalde community and for all Texans.
Texas Senator Ted Cruz said gun reforms were not the way to prevent such crimes.
Speaking to reporters, he said rather than restricting the rights of 'law-abiding citizens', 'going after felons' is what will prevent such crimes. He criticised politicians for trying to 'advance their own political agenda" by calling for gun control.
