The cost of transporting the President for political purposes can be substantial, with Marine One costing $16,700-$20,000 per hour and Air Force One amounting to $200,000 per hour. During an election year, determining the extent of campaign-related travel can be challenging. The campaign is expected to reimburse the federal government for a portion of the expenses, but taxpayers generally bear the bulk of the costs. Biden’s campaign and joint fundraising committee have amassed nearly $6.5 million in an escrow account, while only $300,000 has been paid to the U.S. Treasury for reimbursement. Trump’s campaign reimbursed the government nearly $4.7 million in 2020.
