Lakewood, Colorado (CNN) – A Mitt Romney campaign aide found himself trying to explain the difference between a "finance event" and a "fund-raiser" after reporters were told they would not be allowed to cover a Tuesday evening finance event - or was it a fund-raiser? - with vice presidential candidate Paul Ryan in Las Vegas.
The aide, who insisted on briefing reporters without being named, was disputing reports that the move meant Romney officials were changing the coverage agreement they made with news organizations about covering campaign fund-raisers.

The campaign allows reporters to cover remarks made by Romney at rallies, or at receptions with donors that are held in a public venue. In theory, the same would hold true for Ryan, his new running mate.
Ryan is holding some kind of finance-related meeting Tuesday evening in Las Vegas with GOP mega-donor Sheldon Adelson, but the campaign said Tuesday they will not let reporters cover it.
"Tonight's event is not a fund-raiser. It is a finance meeting. The rules are pretty clear on this," the Romney aide explained to reporters after a Ryan rally in Colorado. "If it's a public venue, for a fund-raiser, we have press there. Given that it is not a fund-raiser, it is a finance meeting, it is closed press."
Peppered with questions seeking clarification on the difference between a "finance event" and a "fund-raiser" - terms the Romney campaign has used interchangeably in the past - the aide repeated the same answer at least seven times.
"This is a finance event, not a fund-raiser," the aide said.
The Romney aide returned a few moments later to attempt to clear it up.
"The difference between a finance event and a fund-raiser is you don't pay money. The difference between a finance event and a fund-raiser is that you don't pay for a ticket to go to a finance event. No money is raised at the finance event."
Does that mean Romney has not actually raised money at past "finance events"? The answer remained unclear.
The meeting with Adelson at The Venetian resort, which was first reported by CNN last weekend, is not on Ryan's official schedule.
Campaigns aren't always forthcoming with information about fund-raisers or finance events so it was no surprise answers were not readily available.
The most detailed answer reporters were able to glean from the aide was that the Ryan meeting is "a Nevada Finance Leadership" event.
