The blackjack dealer who carried on with
Congressman Anthony Weiner online has been placed on leave by her Las Vegas Casino.
Lisa Weiss told TMZ yesterday, it was innocent when it started -- she just liked Weiner's policies. But it turned sexual and she regrets it, even sending an
apology letter to Weiner's wife.
Weiss tells us she got a call from the "big bosses" at the
Bellagio Hotel and Casino yesterday afternoon, informing her if she did anymore interviews she'd be fired. The bosses told her she couldn't come to work for a week, until the "media frenzy" died down.
Apparently what pushed the bosses over the line was that reporters swarmed the casino looking for her.
Rep. Anthony Weiner's Vegas-based cyber mistress felt so bad about her involvement in "Weinergate" -- she typed up an apology letter and mailed it off to Mrs. Weiner ... TMZ has learned.

Lisa Weiss tells
Huma Abedin she wants to express her "deepest apologies for conversing with your husband Congressman Anthony Weiner."
Weiss adds, "I honestly meant no harm and I hope that you and Anthony can work through this."
Before signing off, Weiss noted, "I still remain a huge supporter!"
So we gotta ask ...
The
40-year-old blackjack dealer who carried on a sexual online relationship with
Rep. Anthony Weiner tells TMZ, she regrets ever getting involved with him -- because the scandal is ruining her life.
Lisa Weiss called in to TMZ Live today -- claiming she hasn't been able to leave her Las Vegas house in days ... "I feel guilty being a part of it ... It's messing up my life ... I'm humiliated."
Weiss says she still has a lot of respect for Weiner, and doesn't think the scandal should put his job in jeopardy -- but did admit feeling sorry for Weiner's wife.
What's fuzzy about the whole thing ... is why Weiss released all of her steamy, sexual exchanges with Weiner to a reporter. She insists she didn't release the info to hurt the Congressman, claiming she didn't know it would be that big a deal. Yeah, right.
