President Biden faced a new round of backlash on Twitter for his comments on gun control legislation and 9mm ammo on Memorial Day.

Speaking with reporters outside the White House, Biden told about his efforts to work on gun control legislation with Republicans in Congress following the deadly Uvalde school shooting. While Biden admitted that his executive options are limited, he suggested that 9mm bullets have no "rational basis" to be used for self-defense.

"The .22 caliber bullet will lodge in the lungs and we can get it out. A 9mm bullet blows the lung out of the body. The idea of a high caliber weapon, there is simply no rational basis for it in terms of self-protection, hunting," Biden said.

He also added, "And remember, in the Constitution, the Second Amendment was never absolute. You couldn’t buy a cannon when the Second Amendment was passed. You couldn’t go out and purchase a lot of weapons."

According to the ATF’s Annual Firearms Manufacturing & Export Report, pistols produced in 9mm comprised of approximately 56.8% of new pistols produced in 2019, making up about 42% of pistols produced between 2010 and 2020.

Various Twitter users pointed out the popularity of 9mm bullets on Monday while attacking Biden.

Biden has frequently claimed that the Second Amendment is "not absolute," though the White House has insisted he is not planning to do anything about the Second Amendment itself. In addition, he has often repeated the debunked claim that people were barred from owning cannons when the amendment was passed.

Biden’s comments came one day after the president and first lady visited Uvalde, Texas, to meet with the families of victims and survivors of the Robb Elementary School shooting that killed 19 students and two teachers. He has since repeatedly called for more gun control legislation.
