In a desperate plea for "action" on gun control, President Joe Biden has talked about raising the minimum age for buying a gun following the Texas school shooting that killed 19 children and two adults at an elementary school in Uvalde.

On Sunday, Biden took to Twitter to ask why an ordinary citizen can buy an assault weapon with hundreds of bullets.

"Why should an ordinary citizen be able to purchase an assault weapon that holds 30-round magazines and fires hundreds of bullets in minutes," the president asked.

Biden went on to say that the aftermath of the Texas school shooting in Uvalde was "devastating" to the point that parents of the victims had to do "DNA swabs to identify the remains of their 9- and - 10-year-old kids.

"Enough," the president concluded.

In a separate tweet, Joe Biden commented on the guidelines for buying firearms in Texas.

"In Texas, you can be 18-years-old and buy an assault weapon - even though you can't buy a pistol until you're 21," the president said.

Biden then suggested that if banning assault weapons is out on the table, then the minimum age for buying weapons should be raised.

"If we can't ban assault weapons as we should, we must at least raise the age to buy assault weapons to 21," the president said.

Joe Biden Went to Uvalde in Texas

Last week, Joe Biden traveled to Uvalde, Texas to visit Robb Elementary School, the site of the Texas school shooting.

Biden traveled with First Lady Jill Biden. They laid a bouquet of white flowers to those already placed in front of the school sign. The Bidens reportedly viewed every altar erected in memory of each victim.

The couple also reportedly attended a mass at Sacred Heart Catholic Church, where one of the victims' families was in attendance.

As they were about to leave the church and get into their car, a crowd of about 100 people started chanting, "do something," and Joe Biden replied, "we will."

During a commencement address at the University of Delaware on May 28, Biden also commented about the Texas school shooting.

"We have to stand stronger. We must stand stronger. We cannot outlaw tragedy, I know, but we can make America safer," the president said.

Biden earlier noted that gun control is up to Congress as he cannot "dictate this stuff." The president said it was ultimately up to the House and the Senate to outlaw an assault weapon or strengthen the background check for gun sales.

Joe Biden noted that although he will continue to take "any executive action" he can take, he could still not outlaw a weapon and change a background check, The Hill reported.

"I can't do that," the president said, adding that Congress must act to pass gun control legislation.

Texas School Shooting in Uvalde

At least 19 children and two teachers died after 18-year-old Salvador Ramos entered Robb Elementary School and opened fire with an AR-15 style rifle on May 24.

Tactical officers killed Ramos during a shootout in a classroom after he went on a killing spree at the Texas school.

Despite killing 21 people, Ramos' mother claimed that the 18-year-old shooter was not a "violent person." However, the mother acknowledged that her son did not have many friends.
