(CNN) - Chair of the Democratic National Committee, Rep. Debbie Wasserman Schultz, wrote a letter to Republican National Committee Chairman Reince Priebus Thursday responding to an earlier request from the RNC that Attorney General Eric Holder investigate an "apparent" crime by President Obama.
Priebus accused the president Monday of misusing the White House Map Room to record a fundraising video. A White House spokesman noted the room is part of the White House residence, and therefore not subject to the restrictions placed on official rooms.
But Schultz, D-Florida, put the pressure on Priebus in her letter, asking the RNC and Republican presidential candidates to "forgo accepting contributions from Political Action Committees or federal lobbyists." She also called on presidential candidates to disclose their major fundraisers.
"I have noticed with great curiosity yours and the Republican Party's apparent newfound interest in transparency and accountability as it relates to campaign finance," Schultz wrote in the letter obtained by CNN. "Curious because, after all, the Republican Party has fought in Congress and in the courts virtually every effort over the past decade or more to rein in the influence of moneyed special interests in politics and to require greater disclosure and transparency."
Schultz said the steps would help restore confidence in the political process.
"Should you decline to take these steps, however, some in your own party who have referred to your latest machinations on this issue as 'absurd', 'an embarrassment' and 'laughable' will be confirmed in such an assessment," Schultz wrote.
RNC Spokeswoman Kirsten Kukowski responded to the letter, accusing Schultz of "hypocrisy."
"It's time for Debbie Wasserman Schultz to get off her soapbox considering the DNC takes money from state lobbyists and Wasserman Schultz herself takes money from PACs," Kukowski said. "For the record, the RNC is curious when Debbie Wasserman Schultz became a spokesperson for the DOJ. We will continue to wait for an investigation from them into potentially criminal activity by this president."
