Philadelphia police have arrested two men who were allegedly involved in a plot to attack the Pennsylvania Convention Center on Thursday night.
It's thought the plan was to possibly carry out an attack at the convention center where votes from the election are still being counted, reports Daily Mail.
Police have taken the duo into custody when a weapon was found.
Inside the Convention Center, workers have been tallying hundreds of thousands of votes cast by Philadelphia residents.
In Philadelphia, 358,644 absentee and mail-in ballots have been returned so far. 84 percent of those have been counted, and 58,642 more need to be counted.
Pennsylvania is among a handful of battleground states Trump and Biden are narrowly contesting as they seek the 270 electoral votes needed to win the presidency.
Trump, who held a 675,000-vote lead early Wednesday, prematurely declared victory in the state.
