Joe Biden has renewed a call for Congress to ban assault rifles, including the model that was used in the failed assassination attempt on Donald Trump.

Axar.az reports that Trump's ear was grazed by a bullet after a gunman shot at him from a nearby rooftop during a campaign rally in Pennsylvania on Saturday.

“An AR-15 was used in the shooting of Donald Trump. This was the assault weapon that killed so many others, including children. It’s time to outlaw them,” Mr Biden told the audience at a convention in Las Vegas.

Gun rights are an issue Mr Biden has frequently campaigned on.

In 1994, he was instrumental in passing an assault weapons ban, which expired in 2004. He referenced that legislation during his speech, saying "I've done it before, I'll do it again".

In 2022, during his first term as president, Mr Biden signed into law the most significant gun safety legislation in more than two decades, which included enhanced background checks for gun buyers and other protections.

But he has repeatedly come up against strong opposition from Republicans to an assault weapons ban.
