Yesterday I linked to a Judicial Watch complaint against John McCain about a London fundraiser. That Judicial Watch story is old, not new. Back at the end of April, the McCain campaign told the Hill:

The McCain campaign dismissed the complaint as “completely wrong.”
“That’s what happens when a group files a complaint without calling the campaign to see if its facts are straight,” said McCain spokesman Brian Rogers. “The campaign obviously had an agreement to pay for the space, catering and other costs for the event, and those payments are set to be made in due course. There’s just no issue here.”

I understand the payments will show up on the May FEC report.
