Vice President Kamala Harris made an appearance on "Meet the Press" Sunday morning and was asked by host Chuck Todd to compare the attacks of 9/11 to the "attacks from within" that threaten Democracy today.

"We're at the 21st marking, if you will, of the September 11th attacks," says Todd at the opening of the segment.

"This was a foreign terrorist attacking our Democracy. We're now, as a nation, battling a threat from within. Is the threat equal or greater than what we faced after 9/11?"

"That's an interesting question," Harris says. "I have held many elected offices as district attorney, attorney general, senator and now vice president, and there's an oath that we always take which is to defend and uphold our Constitution against all enemies, foreign and domestic.

We don't compare the two in the oath, but we know they both can exist and we must defend against it."

"It sounds like you think this threat is as great," Todd says, circling back to his initial question related to 9/11.

In addition to Rudolph, the other inactives are center Kendrick Green, receiver Steven Sims, defensive end Isaiahh Loudersmilk and linebacker Mark Robinson.

"I think it is a threat and I think it's very dangerous," Harris says. "I think it is very harmful and it makes us weaker.

I have met with and I've had conversations with over 100 foreign heads of state . . . and when we as the United States walk into those rooms around the world, we have had the honor and privilege, historically, of holding our head up as a defender and an example of a great Democracy.
