The former chairman of the Democratic National Committee has called for Rep. Anthony Weiner to resign. 

"Lying is unforgivable," said Kaine, the first Democrat to call outright for Weiner's (D-N.Y.) resignation. 

Kaine, who is running for retiring Sen. Jim Webb's (D-Va.) Senate seat, said in an interview with a local Virginia television station on Tuesday: "Lying publicly about something like this is unforgivable and he should resign."

Kaine's comments follow Weiner's admission that he sent a lewd picture of himself through Twitter to a female college student in Washington state. At a tearful press conference, Weiner acknowledged he had lied to his family, colleagues and constituents when he initially said his Twitter account had been hacked. 

House Minority Leader Nancy Pelosi (D-Calif.) on Tuesday called for an ethics investigation of Weiner as Democrats sought to distance themselves from the congressman; a number of Republicans have called for Weiner's resignation.

Weiner announced during the same press conference that he had no plans to resign his congressional seat.

A recent NY1-Marist Poll found that a majority of New Yorkers think Weiner should not resign his seat.
