MINNEAPOLIS (AP) - A fired Minnesota state Senate staffer is threatening to expose adulterous affairs by other legislators as part of a potential lawsuit over his firing.

Michael Brodkorb's legal strategy is laid out in a notice of claims filed with the state Tuesday.

Brodkorb was fired in December over an affair with his boss, then-Majority Leader Amy Koch.

Brodkorb says he has a gender discrimination claim because female staffers who had affairs with male legislators weren't fired.

The notice says Brodkorb would seek more than a half-million dollars if he sues.
