Washington ? Former Rep. Eric Massa, who resigned from Congress amid sexual harassment allegations, offered contradictory explanations for his behavior Tuesday, acknowledging he groped a male staffer in a nonsexual way but later denying any groping.

In a pair of TV interviews, the New York Democrat discussed wrestling with male staffers at his 50th birthday party and tickling one of them.

“It doesn’t make any difference what my intentions were, it’s how it’s perceived by the individual who receives that action,” Massa said on conservative commentator Glenn Beck’s Fox News Channel show. “I’m telling you I was wrong. I was wrong. … My behavior was wrong. I should have never allowed myself to be as familiar with my staff as I was.”
