Iran Press/ America: supporters protesting the results banged on glass doors at the Maricopa County Elections Department office in Phoenix, Arizona.
When the voting station was reportedly forced to close to the public, Joe Biden was ahead in the state by roughly 70,000 votes.
A tweet from Maricopa's elections department said: "Staff will continue our job, which is to administer elections in the second-largest voting jurisdiction in the county.
"We will release results again tonight as planned. We thank the (sheriff's office) for doing their job so that we can do ours."
Meanwhile, Trump fans screamed, "stop the vote" while storming a counting site in Detroit on Wednesday.
Some people banged on the glass as workers continued to tally votes.
The guards were heard telling people to "stand back" as the crowd tried to push their way through the door and into the room where election workers counted ballots.
It's now been reported Trump's Justice Department could send armed officers to ballot counting venues to investigate alleged voter fraud.
