Obama calls for reshaping public attitudes towards gun ownership in America.

Former President Barack Obama says gun ownership in America has turned into an ideological issue and a “proxy for arguments about our culture wars,” instead of a safety issue. President Joe Biden is set to convene governors and state lawmakers at the White House to call on them to strengthen gun background checks on buyers younger than 21 years old. This year, there have been 22 mass killings, defined as four or more people killed, not including the perpetrator, according to the USA TODAY/Northeastern University/Associated Press Mass Killings Database.
