In the course of five days this month, eight Planned Parenthood clinics in five states and D.C. reported getting the same visit: A man said he needed treatment for a sexually transmitted disease and then, once alone with a staff member, implied that he ran an interstate sex trafficking ring that involves minors and illegal immigrants.

The Planned Parenthood Federation of America thinks that the visits, which happened between Jan. 11 and 15, are part of a James O'Keefe-style "sting." But the group called in the FBI anyway.
