Democratic National Committee chairwoman Debbie Wasserman Schultz accused Republican National Committee chairman Reince Priebus of hypocrisy Sunday after he called for the resignation of Rep. Anthony Weiner (D-NY), while remaining silent on the sex scandals of Sen. David Vitter (R-LA) and Sen. John Ensign (R-NV).

"What Reince is saying doesn't pass the straight-face test, from a chair of a party who none of its leaders called for Sen. Vitter, who actually broke the law, to resign, who is still serving office," Wasserman Schultz told NBC's David Gregory. "[Vitter] hired prostitutes and evaded the truth. Chairman Priebus was chairman when Sen. Ensign was also embroiled in unethical, unacceptable, and probably illegal conduct, and he did not call for Sen. Ensign to resign."

"Sen. Ensign resigned," Priebus insisted.

"But you never called for his resignation, so it's a double standard," Wasserman Schultz charged. "So, you only call for Democrats' resignation, but not for Republicans', okay."

For her part, the Democratic chairwoman called on Weiner to resign after he admitted sending lewd pictures to several women and lying about it.
