Eric Massa Resigns: Swears it's Policy-Related

NEW YORK (CBS/AP) When a congressman resigns under the cloud of a sexual harassment investigation, one might assume that the reason for his departure was, say, the aforementioned sexual harassment investigation cloud.

Not so, says New York Democratic Congressman Eric Massa. He resigned on Tuesday, but has said it was in fact related to his recent push against health care reform.

In this corner: The Washington Post reports that Massa, who previously denied even the existence of a harassment investigation by saying he just used "salty language" around his staff, is being investigated for groping male staffers. According to the Post, one source described it as "a pattern of behavior and physical harassment." In other words: more than just salty language.

And the challenger: Massa says he was targeted by Democrats who will "stop at nothing" to advance their health care overhaul. On a New York radio station Sunday, Massa blamed Democrats for his downfall, saying, "I was set up for this from the very, very beginning."

Just to summarize the two possibilities for why Massa stepped down: Massive conspiracy vs. a politician behaving badly.
