There are two things Arizona is talking about. First, Fox News is early call awarding the state to Democrat Joe Biden. There are still up to 500,000 to 600,000 ballots yet to be counted in the state as President Trump has chipped away at Biden's lead here.
The second is the sharpie.
Social media users are saying their ballots were not scanned in Arizona because they were given Sharpies. The Secretary of State's Office is attempting to explain this.
There have also been concerns posted on social media about some Arizonans ballots being canceled. Seeing canceled on the Secretary of State's website means you received a mail-in ballot but chose to vote in person.
