Democratic nominee Hillary Clinton said during the second presidential debate Sunday night that she would nominate Supreme Court justices who advocate stricter gun laws.

"I respect the Second Amendment, but I believe there should be comprehensive background checks, and we should close the gun show loophole and close the online loophole. We have to save as many lives as we possibly can," Clinton said.

Although the issue of gun control was talked about only briefly during the second debate, it has been one of Clinton's major themes.

The Democratic nominee said during the first debate, "We've got to get guns out of the hands of people who should not have them. The gun epidemic is the leading cause of death of young African- American men, more than the next nine causes put together . . .

"We've got too many military-style weapons on the streets. In a lot of places, our police are outgunned. We need comprehensive background checks, and we need to keep guns out of the hands of those who will do harm," she continued.

"And we finally need to pass a prohibition on anyone who's on the terrorist watch list from being able to buy a gun in our country. If you're too dangerous to fly, you are too dangerous to buy a gun."

Clinton also told AARP in a recent interview that when she considers ways to combat terrorism, she also looks at the problem of violence broadly, because "it's not only terrorists we need to be worried about. Terrorism is part of it, but gun violence kills 33,000 Americans a year."
