President Biden called on Congress to ban assault weapons or to raise the age to be able to buy one from 18 to 21 and other measures to curb gun violence in the United States in an address Thursday night.

"If we can't ban assault weapons then we should raise the age to purchase them from 18 to 21," Biden said.
