President Joe Biden called for AR-15 guns, the type used in the attempted assassination of Donald Trump, to be banned during a fired-up NAACP National Convention speech. “It’s time to outlaw them. I did it once, and I will do it again”, Biden said during his speech on Tuesday (16 July) In 1994, Congress passed the Federal Assault Weapons Ban, prohibiting certain semi-automatic assault weapons as well as large-capacity ammunition-feeding devices. It expired in 2004. A bullet clipped Trump’s right ear when gunman Thomas Matthew Crooks opened fire at the former president’s rally in Butler, Pennsylvania on Saturday (13 July).
