President-elect Donald Trump still has an unpaid bill from the city of Tucson.
Trump, who held a rally at the Tucson Convention Center back in March, owes $81,837 to the city for event security at the rally.
While the city sent a demand letter to Trump's campaign in September, the debt is still outstanding.
A subsequent Oct. 27 letter from Trump's lawyer, Donald McGahn, notes that the campaign did not request Tucson police to "provide public safety" at the rally.
The city also has yet to receive payment from Bernie Sanders. The Vermont senator owes $44,013 in event security costs for his March rally at the convention center.
His lawyer also argues that the campaign did not request police's assistance during the rally.
A spokeswoman with the Tucson city manager's office tells ABC15 that no decision has been made yet concerning litigation against both campaigns.
Lawyers for both Sanders and Trump could not be reached for comment Wednesday.
