A thank you present of pineapple-shaped cookies delivered to the Wake County Board of Elections in North Carolina prompted a hazmat response on Tuesday after election workers raised concerns about a suspicious package mailed from Hawaii.

“We are just on high alert with these things automatically,” said Wake County elections specialist Danner McCulloh, who cited recent incidents of suspicious packages containing powder sent to election offices across the country.

The Raleigh Police and Fire Departments quickly responded to the incident and bomb technicians x-rayed the package, according to Lt. Jason Borneo of the Raleigh Police Department.

After the package was deemed to not be a threat, emergency responders opened the package to learn it was full of cookies shipped from the Honolulu Cookie Company. The operations at Wake County Board of Elections were not impacted during the incident, a county spokesperson said.

According to McCulloh, a person who heard a radio story about Wake County decided to send the cookies unannounced to thank election workers.

“It was a kind gesture,” McCulloh said, though he recommended against others sending cookies to his office.

Harris brought her “closing argument” to Harrisburg, Pennsylvania, Wednesday, highlighting what she said is a clear contrast between her and Trump, and encouraging voters to cast their ballots in the election’s final days.

“We know we have an opportunity in this election to turn the page on a decade of Donald Trump trying to keep us divided and afraid of each other. That is who he is. But Pennsylvania, that is not who we are,” Harris said, swapping out "America" for "Pennsylvania" from her speech at the Ellipse the night before.

Harris was interrupted several times by pro-Palestinian protesters.

“We are six days out of an election. We are six days away from an election. And ours is about a fight for democracy. And your right to be heard. That is what is on the line in this election. That is what is on the line in this election,” Harris said as she was being jeered by a protestor holding up a large Palestinian flag.

“Look, everybody has a right to be heard. But right now, I am speaking. And one of the biggest issues that folks around the country want to talk about and hear is about how we are going to bring down the price of living for working people," she said.

Two Pennsylvania voters and the state's Democratic Party asked the U.S. Supreme Court on Wednesday to reject a Republican request to block counting of provisional in-person ballots cast by people whose mail-in ballots were not put into a required security envelope.

The Democrats argued the Pennsylvania Supreme Court delivered a "straightforward" decision that state law permits voters whose mail ballots were not counted to "exercise their statutory right to vote provisionally rather than be disenfranchised altogether."

The party contends that the RNC has no standing to bring a challenge in the case because it involves two ballots from the 2024 Democratic primary in which the Republican Party could not have been "injured."

They also argued that the so-called Purcell principle -- of nonintervention by courts close to a voting period -- does not apply to state courts.

The Democrats also said the Republicans' request for segregation and non-counting of provisional ballots would be a "sweeping" intervention and imposition on county boards of election which are not even parties to the case.

Authorities in Michigan charged an unidentified non-U.S. citizen with allegedly illegally registering to vote and casting a ballot.

More specific details about the case, which took place in Ann Arbor on Sunday, were not immediately available.

The case was referred to law enforcement by a clerk, according to Michigan Secretary of State Jocelyn Benson and Washtenaw County Prosecutor Eli Savit.

"We are grateful for the swift action of the clerk in this case, who took the appropriate steps and referred the case to law enforcement. We are also grateful to law enforcement for swiftly and thoroughly investigating this case," they said in a joint statement.

"Noncitizen voting is an extremely isolated and rare event. Investigations in multiple states and nationwide have found no evidence of large numbers of noncitizens registering to vote. Even less common is a noncitizen actually casting a ballot," they added.
