This video is super awkward ... Anthony Weiner was put on BLAST Friday by an ex-school teacher for his raunchy, sexting ways ... and it all happened while cameras rolled.
Weiner was visiting homes damaged by Superstorm Sandy, when he walked into a s**t storm himself ... in the form of Peg Brunda a retired teacher, who went off on him.
You gotta watch the heated exchange -- but to give you an idea just how PISSED Brunda is that Weiner refuses to drop out of the NYC mayoral race, she says, "Had I conducted myself in the manner in which you conducted yourself, my job would have been gone."
Then adds, "I don’t quite understand how you would feel you would have the moral authority as the head administrator in this city to oversee employees when your standard of conduct is so much lower than the standard of conduct that’s expected of us."
Weiner tries to fire back ... but Peg doesn't back down. Check it out.
