CLARENCE, New York -- A married upstate New York congressman accused of sending a shirtless photo of himself to a woman abruptly resigned Wednesday, saying he regretted the actions that had hurt his family and others.

The gossip website Gawker reported Wednesday that Rep. Christopher Lee, a two-term Republican with a young son, had e-mailed the photo to a woman he met on the Craigslist classified-ads website.

Lee said in an e-mailed statement that his resignation was effective immediately. The statement offered no confirmation or details of a Craigslist posting.

“I regret the harm that my actions have caused my family, my staff and my constituents,” Lee said in a statement posted on his congressional website. “I deeply and sincerely apologize to them all. I have made profound mistakes and I promise to work as hard as I can to seek their forgiveness.”

Lee said the challenges faced in western New York state, where he serves the 26th Congressional District, and across the country are “too serious for me to allow this distraction to continue, so I am announcing that I have resigned my seat in Congress effective immediately.”

Lee's resignation comes almost a year after Democrat Eric Massa resigned his seat in western New York's 29th Congressional District amid an investigation into whether he sexually harassed male staffers. Massa gave contradictory explanations for his behavior, acknowledging he groped and tickled a staffer in a nonsexual way and wrestled with others at his 50th birthday party but then denied any groping occurred.

In Lee's case, a woman described as a 34-year-old Maryland resident and government employee provided Gawker with e-mails she said were an exchange between her and Lee in response to an ad she placed last month in the “Women Seeking Men” section of Craigslist, the classified-ads website.
