President Joe Biden said on the White House lawn on Monday that the Second Amendment was never meant to be absolute.

The president also provided his explanation of the differences in calibers of bullets, providing his expert analysis of why .22 and 9mm bullets are different.

“A .22 caliber bullet will lodge in the lungs and we can probably get it out and save a life. A 9 mm bullet blows the lung out of the body, but the idea of these high caliber weapons … there’s simply no rational basis for it in terms … of self-protection, hunting… the constitution, Second Amendment, was never absolute,” he said.

Biden said that he had hopes that the public opinion has shifted as of late towards being more lenient on gun control, saying that he thinks “things have gotten so bad that everybody’s getting more rational, at least that’s my hope.”

Biden’s words came after he met with the families of those in Uvalde, Texas after the massacre at Robb Elementary school, where 19 students were killed along with two teachers.

“The Second Amendment was never absolute,” Biden told the press. “You couldn’t buy a cannon when the Second Amendment was passed. You couldn’t go out and buy a lot of weapons.”

When asked if he felt more motivated because of recent events that have taken place, he said “I’ve been pretty motivated all along. I’m going to continue to push and we’ll see how this goes.”

Biden added that “it makes no sense to be able to purchase something that can fire up to 300 rounds” and said that “the idea of these high powered weapons, there’s simply no rational basis for it.”
