The invitation asked partygoers to give anywhere from $500 to $10,000 to the North Carolina Democratic Party.
"It's not illegal, but it's unethical, and it's not upfront with North Carolina voters and that's what they expect of our Governor and our leaders," offered North Carolina Republican Party Spokesman Brent Woodcox.
Woodcox said he's concerned the Democrats are going to use the donations to pay off Perdue's more than $900,000 loan to her campaign.
"Once they put this money into the general fund, really they can use it for anything legal under the sun. And one of those things is paying off campaign debt. This is a rather transparent attempt to take in money with unlimited amount that they couldn't give directly to pay off campaign debt to the party for that use," he told Eyewitness News.
The North Carolina Democratic Party sent Eyewitness News this statement:
"We are delighted to have Governor Perdue's support in helping the Democratic Party raise funds after this hard fought election season. The funds raised by the Party will not be earmarked for any particular purpose. They will be used to support party programs and activities."
But the GOP is not convinced.
"We're just trying to put Governor Perdue on notice that until she fulfills her promises, we going to be watching and we're going to hold her to them," said Woodcox.
