Wisconsin Gov. Scott Walker revealed pressure tactics, unwillingness to compromise, views on protesting crowds and his inspiration in tough budget talks in a call with a prank caller prentending to be a conservative billionaire activist on Tuesday.

The call, which lasted at least 20 minutes took place with Ian Murphy, a writer for a website called the Buffalo Beast, who pretended to be political financier David Koch. Audio was posted online.

Walker spoke of tentative ways to pressure Senate Democrats absent from their jobs, efforts to assuage lawmakers concerned about huge crowds of protesters, thinking about but ultimately deciding against placing troublemakers among the protesters, and drawing inspiration from former President Ronald Reagan's tough actions against striking federal employees at the beginning of his presidency.
