A North Carolina appeals court on Tuesday rejected a Republican-led effort to block ballots cast by overseas voters unless they could provide additional proof of their residency in the state.

The Republican National Committee sued the North Carolina State Board of Elections earlier this month over a policy that allows voters living abroad to cast their ballot in the state if their parents previously lived in North Carolina, even if the voter never resided in the state themselves.

A trial judge last week denied the RNC's request to stop the policy, and their appeal of that decision was unanimously rejected by a panel of three judges on the North Carolina Court of Appeals Tuesday.

The Republican National Committee -- joined by the state party and two voters -- argued that the policy "flies in the face of the state constitution" by allowing non-residents to participate in the state’s elections.

"North Carolina has notoriously close elections," the lawsuit said. "Now more than ever, counting every legitimate vote from every eligible voter -- and only legitimate votes from eligible voters -- matters."

The North Carolina State Board of Elections highlighted that the policy has been in place for over a decade without issue, arguing the injunction requested by the RNC would "disenfranchise an entire class of lawful voters."

"Petitioners’ petition represents an unwarranted and unprecedented effort to disrupt an ongoing election by throwing countless voters’ duly cast ballots into question with no actual proof of any problem with them," the state said in their filing.

The case is yet another legal setback for Republicans, who lost a similar case in Pennsylvania earlier Tuesday.

Multiple pro-Palestinian protesters were escorted out at separate points by security during Vice President Kamala Harris' remarks on Tuesday night at the Ellipse in Washington, D.C.

The protesters, who ABC News saw inside the Ellipse, were staging small protests calling for an arms embargo on Israel. One protester was escorted out right near the stage.

Vice President Kamala Harris' closing argument took hits at her opponent, former President Donald Trump, but made a case for voters on both sides of the political aisle.

"Unlike Donald Trump, I don’t believe people who disagree with me are the enemy. He wants to put them in jail; I’ll give them a seat at the table," Harris said, referencing her campaign platform to include a Republican in her cabinet if elected.

"I pledge to you to approach my work with the joy and optimism that comes from making a difference in peoples' lives," Harris said.

"And I pledge to be a president for all Americans -- and to always put country above party and self," Harris added.

Vice President Kamala Harris stressed former President Donald Trump's role in the attack on the U.S. Capitol on Jan. 6, 2021, while standing on the same stage he did that preceded the riot.

"We know who Donald Trump is. He is the person who stood at this very spot nearly four years ago and sent an armed mob to the United States Capitol to overturn the will of the people in a free and fair election," Harris said, adding, "An election that he knew he lost."

"Americans died as a result of that attack. 140 law enforcement officers were injured because of that attack," Harris said.
