Rep. Anthony Weiner, D-N.Y., says he's sorry. Evidently, though, he's not sorry enough to resign from the House. Prominent Democrats should convince him to change his mind.

So far, Minority Leader Nancy Pelosi, D-Calif., has called for only an ethics investigation of the disgraced congressman, whose sordid scandal has provided abundant fodder for late-night TV comics.

On Monday, Rep. Weiner, widely touted as New York City mayor material, admitted lying last week when he denied sending a crude photo of himself to a young woman over the Internet. He also conceded that he had similarly inappropriate communications with five other women over the past three years.

When Rep. Pelosi became House speaker in 2007, she promised to run "the most ethical Congress ever."

Sending gross pictures of yourself to people you don't know -- and whose ages you don't know -- is not ethical.

Rep. Pelosi has demanded an investigation to determine whether Rep. Weiner used any government assets in these appalling communications.

However, Rep. Weiner said Monday that he broke no laws and intends to remain in Congress as long as his constituents support him.

He also said, "This was me doing a dumb thing, and doing it repeatedly, then lying about it."

Yet what he did was far worse than dumb -- even if he hadn't lied about it.

Losing your keys is "doing a dumb thing." Sending vulgar pictures of yourself to women is doing a disgusting thing unworthy of a member of the U.S. House.

Now it's up to Minority Leader Pelosi and other top Democrats to clean House by convincing -- forcing, if needed -- Rep. Weiner to do the right thing and resign.
