People going overseas and becoming radicalized, coming back maybe people have an increased interest in weapons.

I think it's a big disservice to our country and to our democracy to continue to raise these doubts.

And I'm hoping that between now and two years from now and four years from now and future election cycles, people have gotten past the hype and the hysteria of these most recent allegations.

Let's remind ourselves that offering an opportunity for somebody to register to vote at the Department of Motor Vehicles has been required by federal law for decades now. We know it as motor voter. So whether it's motor voter and people registering on paper or online voter registration, we have the protocols in place to keep people who are not eligible to register to vote from registering, whether it's for citizenship status, whether it's for age or any other reason.

All of us in a bipartisan manner went out of our way to explain to the voters how our election systems are secure, the fact that voting systems are not connected to the Internet - not the machines that we use to mark ballots, not the machines that we use to count ballots, the fact that our election counting procedures are very transparent.

If California is any indicator, I'm proud that the public here saw right through it and registered in record numbers and voted in record numbers.

Donald Trump and his team have not provided any evidence of widespread fraud in this year's election.
