“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 we can do to stop them,” Obama told CBS News.

Sen. Dianne Feinstein went even further in her call for Congress to change gun laws.

“When a terrorist who can’t board an airplane can buy an assault rifle in a gun store, that’s a problem,” Feinstein said in a statement. “Congress can’t stop every shooting, but we can help reduce their frequency.”

Sen. Barbara Boxer said it’s heartbreaking to see another mass shooting in the country.

“It’s not enough to keep lamenting these things,” she said. “We have to take action.”
