US President Joe Biden has called for a ban on assault weapons and tighter gun control measures after a mass shooting left 10 people dead in Colorado.
“I don’t need to wait another minute, let alone another hour, to take common sense steps that will save lives in the future,” Biden said, adding that “we can ban assault weapons”.
“This is not and should not be a partisan issue,” Biden said at the White House.
“It’s an American issue that will save lives, American lives. We must act.”
“We can ban assault weapons and high capacity magazines in this country, once again.”
Biden spoke before leaving Washington DC for Columbus, Ohio, a visit where he will mark the 11th anniversary of the signing of the Affordable Care Act known as Obamacare.
The mass shooting in Boulder followed a gunman’s killing the previous week of eight people at spas in Atlanta, bringing new attention to US gun violence.
Flags at the White House were at half staff until sunset on Monday to commemorate the Atlanta shooting victims.
They flew at full staff for a few hours on Tuesday morning before being lowered again to mark the Boulder killings.
Biden, whose personal life has been marked by the loss of his first wife and two children, offered his condolences to the families of victims, saying he and his wife Jill Biden were devastated by the deaths.
Any effort to move the US toward greater gun control has historically been difficult with his fellow Democrats in favour and Republicans largely opposed.
