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."
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.
