New Hampshire Sens. Jeanne Shaheen and Maggie Hassan are calling on their state's secretary of state, Bill Gardner, to resign from President Trump's voter fraud commission following a Breitbart op-ed by the commission's leader, Kris Kobach.

On Thursday, Kansas Secretary of State Kobach published an op-ed in Breitbart alleging over 5,000 votes were cast illegally in the 2016 election using out-of-state IDs, tipping the election in favor of the Democrats. New Hampshire House Speaker Shawn Jasper said he sought the statistics used by Kobach, a strong proponent of strict voter ID laws, for future changes to voter laws.

New Hampshire law allows people, such as out-of-state college students, to register without a state ID. It also allows people to register to vote on Election Day. The secretary of state's office is responsible for verifying election results.

"Now, the head of President Trump's misguided commission is using deceiving and irrelevant data to rehash the same false claims," the Democratic senators said in a statement. "Secretary Gardner's association with this partisan commission risks tarnishing his long legacy of fighting for the New Hampshire Primary and promoting voter participation."

Gardner told New Hampshire Public Radio he won't step down from the commission.

"I'm not going to quit from a committee because I don't agree with some people," he said.

Hillary Clinton defeated Donald Trump in the state by 2,736 votes. Hassan defeated then-Republican Sen. Kelly Ayotte by 1,017 votes. The races, in part, prompted Trump to decry "millions" of illegal votes cast in the 2016 election, though there has been no evidence of widespread voter fraud presented.

Numerous states said they won't comply with the commission's request for voter registrations, which include the last four digits of Social Security numbers and other identifying information. Gardner said he will send publicly available data to the administration.

Many Democrats, including Senate Minority Leader Chuck Schumer, have called for an end to the commission entirely.

"Many of us found the Election Integrity Commission distasteful when it was first created," Schumer said in August.

The second meeting of the Presidential Advisory Commission on Election Integrity is set for Tuesday morning at Saint Anselm College in Manchester, N.H.
