Joe Biden delivers gun-safety speech hours after son’s firearm conviction

President sought to rally support around issue but speech was briefly interrupted by pro-Palestinian protesters

Joe Biden, facing a backlash from young voters over the war in Gaza, sought to rally support around the issue of gun safety just hours after his son Hunter was convicted of lying about his drug use to illegally buy a firearm.

Contrasting his record with election rival Donald Trump, the US president brought an audience that included many students to its feet at the Everytown for Gun Safety Action Fund's annual Gun Sense University conference in Washington on Tuesday.
