The Kansas official in charge of a multi-state voter registration 'crosscheck' program said Monday that on Election Day, 6,000 people registered to vote in New Hampshire using drivers licenses from other states.

Nearly half of those suspect cases involved licenses issued in Massachusetts.

That, Kris Kobach told CNN, supports the White House's contention that America's voting system suffers great enough incidence of fraud to swing an election.

CNN conducted the interview over a graphic that read: 'Zero evidence to support Trump voter fraud claims.' Kobach later tweeted that it was 'proof of @CNN bias.' They run text below my picture claiming my statements are false. So much for letting the viewer decide.'

New Hampshire Democratic Sen. Maggie Hassan unseated Republican incumbent Kelly Ayotte in November by just 1,017 votes, out of more than 707,000 cast.

White House Senior Policy Adviser Stephen Miller argued in an a series of Sunday morning interviews that 'thousands' of Massachusetts voters from were 'brought in on buses' to vote 'illegally' in that contest.

Kansas Secretary of State Kris Kobach said Monday that on Election Day, 6,000 people with out-of-state drivers licenses registered to vote in New Hampshire – creating a real possibility of fraud in a U.S. Senate race that was decided by a 1,017-vote margin

White House Senior Policy Adviser Stephen Miller said Sunday that President Trump's claims that Massachusetts voters were bussed into New Hampshire on were 'very real'

'Having worked before on a campaign in New Hampshire, I can tell you that this issue of busing voters in to New Hampshire is widely known by anyone who's worked in New Hampshire,' Miller said on ABC. 'It's very real. It's very serious.'

The squabble over New Hampshire erupted this week during a closed-door White House meeting in which Trump told Ayotte he thought her close defeat – and his own loss there – was the product of voter fraud.

Miller was sent out on Sunday to defend him.

Ayotte was in Washington as a former senator to help the Trump administration smooth Judge Neil Gorsuch's landing on Capitol Hill in advance of his Supreme Court confirmation hearing.

Kobach, the Kansas secretary of state, organized the Interstate Crosscheck Program, a cooperative 30-state initiative that compares voter registrations in an attempt to void inactive and obsolete entries as people move from place to place.

He was also on a short-list to become Homeland Security secretary in the Trump administration.

'I just got off the phone with the New Hampshire secretary of state, Bill Gardener,' Kobach told CNN anchor Kate Bolduan on Monday.

'New Hampshire is a same-day registration state. And on election day, Nov. 8, 2016, 6,000 people registered in New Hampshire using an out-of-state driver's license as their form of identification,' he said.

'Of those 6,000 – over 6,000 – just under 3,000, so just under half, used a Massachusetts driver's license.'

Miller got into a back-and-forth with ABC's George Stephanopoulos over new voter fraud claims Trump made to senators this week

Kobach acknowledged that 'some of those are going to be legit,' including people who moved to New Hampshire on or before Election Day. But he insisted that some in that group voted illegally in more than one state.

'We do know that a lot of people did that, and we will have data at the end of the month,' he promised.

New Hampshire election law permits people with out-of-state ID to participate in elections if they attest that they maintain a 'domicile' in the state – meaning 'an intent to maintain a single continuous presence.'

Poll workers, however, do not ask for proof.

Bolduan insisted that Kobach's pending analysis doesn't yet support Miller's claim that 'thousands' actually committed voter fraud by being bussed across a state line.

'Voter registration programs does not equal fraudulent votes,' she said, calling Republican alarms 'irresponsible.'

'It's like the Yeti. you can keep talking about it, but you're not going to find it,' Bolduan declared.

Kobach responded that some voter fraud likely took the form of mail-in votes from Massachusetts residents who had traveled north nine months earlier for campaign work during the New Hampshire Primary season.

And he disclosed that as the chief law enforcement officer in Kansas, he has prosecuted criminal voter-fraud cases.

Kobach says he has prosecuted 9 cases of voter fraud so far; he organizes a 30-state project that compares voter registration databases

'I just got that prosecutorial authority a year and a half ago. We've already filed nine cases, and we have six guilty pleas,' Kobach said, noting that Kansas is a small state. 'And the nine cases are just the ones at the top of the list.'

President Donald Trump has made repeated claims about widespread voter fraud, suggesting it numbered in the millions and cost him a symbolic popular-vote victory in November.

The White House has provided no evidence to the Federal Election Commission to support that claim. Trump has promised to sign an executive order aimed at determining the size of the problem.

Miller told ABC on Sunday that 'many, many highly qualified people, like Kris Kobach, the Kansas secretary of state, have looked deeply into this issue and have confirmed it to be true and have put together evidence.'

'And I suggest you invite Kris Kobach onto your show and he can walk you through some of the evidence of voter fraud in greater detail,' he told 'This Week' host George Stephanopoulos.

'We should stop the presses and as a country we should be aghast about the fact that you have people who have no right to vote in this country registered to vote, canceling out the franchise of lawful citizens of this country,' Miller continued. 'That’s the story we should be talking about!'

'And I’m prepared to go on any show, anywhere, any time, and repeat it and say the President of the United States is correct, 100 percent,' he said.
