Sen. James Lankford:

There's a lot of varieties now.

Really, what we're trying to do is say, we should be able to audit an election, that after the election is over, we should be able to evaluate. If we find out that some outside entity was trying to interfere in the election, everyone will immediately back up and say, did they get in?

So there has to be able to have a way to verify that. So, it could be a paper ballot, an optical scanner. It could be a digital machine, as some of them have now, that you punch in your ballot and it prints a piece of paper to confirm, is this what you really voted? You push yes, and then it locks off a paper ballot, as well as your electronic.

There are lots of ways to do it. We just — we're not telling the states how to do it. The states run their own elections. We're just saying there should be a way to audit an election after it's over to make sure that we can verify, if they were attacked in a cyber-means, there is a way to be able to verify we actually have an accurate result.
