Confronted with yet another mass shooting, President Obama again called for more effective gun control Wednesday.

Obama was briefed throughout the day as events unfolded in San Bernadino, California, by his homeland security adviser.

Later, in an interview with CBS, Obama spoke about the pattern of mass shootings the U.S. is facing.

Obama said it was too early to know the shooters’ motives, but he urged Americans to push for legislative action. He told CBS that stricter gun laws, including stronger background checks, would make the country safer.

“The one thing we do know is that we have a pattern now of mass shootings in this country that has no parallel anywhere else in the world, and there’s some steps we could take, not to eliminate every one of these mass shootings, but to improve the odds that they don’t happen as frequently,” Obama said.

According to the New York Daily News, since taking office, Obama has made at least 12 public speeches in response to such shootings. He has also issued 15 statements in response to gun violence.

In the CBS interview, Obama said he was concerned that “we have a no-fly list where people can’t get on planes, but those same people who we don’t allow to fly could go into a store right now in the United States and buy a firearm and there’s nothing that we can do to stop them. That’s a law that needs to be changed.”
