HANOVER, N.H. - Presidential candidate Sen. Kamala Harris says she supports putting a third gender option on federal identification cards.

The Democrat from California backed the idea when asked about it during a town hall Tuesday in the first-in-the-nation presidential primary state of New Hampshire.

“It’s a simple point. There needs to be another category. And I’m open to the idea of doing that. And I think that it’s a good idea,” Harris told Fox News and New Hampshire’s Concord Monitor during an interview later in the day.

HARRIS JOINS WARREN IN CALLING FOR IMPEACHMENT PROCESS TO BEGIN

Harris, a former California attorney general and San Francisco district attorney, has long fought for LGBTQ rights, including refusing to defend a ban on same-sex marriages.

Harris joins 2020 Democratic nomination rival Sen. Kirsten Gillibrand of New York in pushing for a third option on IDs. Four states – California, Oregon, Washington, and New Jersey – have embraced nonbinary IDs – as has New York City.

HARRIS PLEDGES EXECUTIVE ACTION ON GUNS

One day after unveiling her plan to implement stricter background checks on gun sales with or without action from Congress, Harris highlighted her plan at town halls at Keene State College and Dartmouth College.

“One very reasonable approach is that we need to have background checks,” Harris told Fox News, as she vowed to take action as president if Congress failed to act

Harris said that if a bill from Congress did not make it to her desk, she would unilaterally mandate background checks for customers purchasing firearms from any dealers who sell more than five guns a year.

Dealers who violate the law, she said, would have their licenses revoked. The other executive orders would prohibit fugitives from purchasing a firearm or weapon, as well as closing the loophole allowing some domestic abusers to purchase firearms if the victim is an unwedded partner.

Harris pointed to a lack of congressional action after mass shootings across the country the past decade.

“There’s so many examples of absolute tragedies and yet Congress has not acted. So, my point is this – when elected, I’ll give Congress the opportunity, but if they don’t act, I’ll act. And, I believe that is reflective of where the American public is. They want reasonable gun safety laws,” she stressed.

Asked how such a move would be received in a state such as New Hampshire, where the rights of gun owners are well guarded, Harris explained she believed “most people understand – gun owner or not gun owners – that we need reasonable gun safety laws in our country. That’s what this is targeted at.”

She continued, “I’m very clear in my mind – I think most people are – that it’s a false choice to suggest that you're either in favor of the Second Amendment or you want to take everyone’s guns away.”

Harris is now calling on the Democrat-controlled House of Representatives to launch impeachment proceedings following the release last week of the report by Special Counsel Robert Muller on the Russia investigation.

“I believe the process should begin. Where it ends up, I don’t know, but there’s no question that the Mueller report, what we know of it, has outlined facts that leads one to reasonably believe that obstruction occurred,” Harris said.

Asked if such a move would bolster President Trump’s claims that impeachment would be a purely political move by Democrats, which could potentially help his re-election effort, Harris said, “I don’t know what his playbook is.”

LATEST 2020 POLLS IN CRUCIAL PRIMARY STATE

Harris’s return to New Hampshire marked her second visit to the crucial early voting state since she launched her presidential campaign last January. It comes as South Bend, Ind., Mayor Pete Buttigieg – a one-time 2020 long-shot – has surged over the past month and soared above Harris in many public opinion polls – including two of the most recent in New Hampshire.

Asked if she was concerned, Harris said, “the only polls that matter are on Election Day. Period.”

Harris was interviewed before the town hall at Dartmouth. She spoke and took questions from a capacity crowd of more than 400. Minutes earlier, the senator went outside to a speak with an overflow crowd of a couple hundred.

Harris stopped in Claremont on her way from Keene to Hanover. The brief visit included a stop at the Uptown Bakery, where the candidate chatted with employees and customers and bought donuts and pastries for her staff.
