Republican National Committee Chairman Reince Priebus on Sunday accused former Secretary of State Hillary Clinton of trying to whitewash her role in the Sept. 11 terrorist attack in Benghazi, Libya ahead of a possible bid for the White House.

“She played a part in the White House's cover-up of what this is all about,” Priebus said on “Fox News Sunday,” when asked about a chapter in Clinton's upcoming book, which accused the GOP of politicizing Benghazi.

“Hillary Clinton is politics 24/7 – and this is no different,” Priebus added of the book.

The GOP leader ripped Clinton for initially blaming the terrorist strike on a spontaneous reaction to an anti-Islam video, saying the former first lady was trying to “save her own hide by perpetrating this lie.”

Democrats, however, accused Priebus of ignoring the numerous congressional investigations into what happened in Benghazi.

"RNC Chairman Reince Priebus sounded more like a conspiracy theorist than a leader of the Republican Party," said Michael Czin, national press secretary for the Democratic National Committee.

"The Obama administration and Democrats are focused on making sure a tragedy like what happened in Benghazi never happens again," Czin added. "Republicans are obsessed with playing politics with that tragedy just to rally their far-right base."

Clinton’s book, “Hard Choices,” will be released on June 10. However, her camp leaked portions of the book to Politico in an attempt to insulate her from political attacks on Benghazi.

Priebus said Clinton, not then-United Nations Ambassador Susan Rice, should have given the administration's response to the Benghazi strike on the Sunday talk shows. Of her now-infamous remarks, Rice said Clinton didn't discuss Benghazi because she was tired from a grueling week.

The RNC leader said that episode should disqualify Clinton from running for president.
