A small group of angry demonstrators attempted to barge inside the TCF Center in Detroit on Wednesday afternoon, chanting "stop the count" as votes in the battleground state were being tallied, a spokesperson for the city's police department told ABC News.
Michigan election laws permit registered voters in the state to observe ballot counting with approval, though it's unclear if that was the group's intent.
"Election challengers may be appointed by political parties and qualified interest groups to observe the election process," the law states. Once approved, the challenger must abide by several rules, including one where they must wear an official credential while observing the count.
In photos and videos that went viral on social media, the group appeared to bang on the glass walls to be let in. Despite the commotion, Kirkwood said there were "no major concerns."
"Everything is manageable. There are people out there chanting, but that's about it," Kirkwood told ABC News.
A poll challenger was removed from the ballot counting room by police, according to a videographer from Detroit ABC affiliate WXYZ who was inside. However, Detroit police told ABC News that they did not make any arrests from the TCF Center.
Earlier in the day, the Macomb County GOP encouraged supporters to stop by the TCF Center, urging "all hands on deck!," according to an email that was obtained by ABC News.
"Trained Poll Challengers and or Volunteers willing to be trained needed immediately at TCF Center (Cobo Hall)," the email read.
The Macomb County Republican Party didn't immediately return messages to ABC News to comment on Wednesday's incident.
The convention center is the major ballot processing location in Detroit, and ballots were still being counted in the key swing state. It is not clear exactly how many members of the group were at the TCF Center, and it was not clear who they were affiliated with.
ABC News projected that former Vice President Joe Biden will win the state of Michigan as the Democratic candidate led Trump 49.8%-48.6% -- or a difference of 61,237 votes -- with 97% of the votes tallied.
In New York, 20 people were arrested by the New York City Police Department after attempting to "hijack a peaceful protest by lighting fires, throwing garbage and eggs" in Manhattan Wednesday night, according to authorities.
"We appreciate and value the importance of freedom of speech," NYPD said in a statement.
Police said they confiscated knives, M80 fireworks and a taser from the protests Wednesday night in the city.
"Bringing weapons to peaceful protests cannot and will not be tolerated. We are currently working to de-escalate the situation. Anyone caught with a weapon will be arrested," NYPD said.
