Joe Biden once again called for new gun control measures after a mass shooting in Maine that killed 18 people.

"Who the hell needs an assault weapon that can hold, in some cases, up to 100 rounds?" Biden said at a campaign reception on Friday.

"I once again call on Republicans in Congress to fulfill their obligation to keep the American people safe," Biden said late Friday, after the suspected gunman Robert Card was found dead of an apparent self-inflicted gunshot wound.

"Until that day comes, I will continue to do everything in my power to end this gun violence epidemic. The Lewiston community — and all Americans — deserve nothing less," he added.
