(BUZZFEED) — Nine news outlets that covered the election sent a joint letter Monday to former Romney campaign officials to contest expenses billed to their reporters.

BuzzFeed, which is among the outlets that signed the letter, first reported on the dispute last week.

The outlets are requesting that the campaign provide a specific price breakdown for every event that cost them $200 or more. Until then, the letter reads, “some of our organizations have alerted American Express that we are contesting these charges.”
