A nugget buried in the must-read Guardian John Doe story:

good example of the way things worked was the donation made by Donald Trump. On 3 April 2012, two months before the governor faced the electorate, Walker flew to New York for a rapid-fire string of fundraising meetings with big money interests.

He travelled the length of Fifth Avenue in Manhattan, making stops at the investment bank Morgan Stanley, a hedge fund, a corporate law firm, and the residence of publishing tycoon Steve Forbes. He also enjoyed a 45-minute audience with Trump in his Fifth Avenue lair.

There is no record of the conversation between the two men. But it appears to have been a warm encounter, as the John Doe files show that Trump wrote a check for $15,000 on the same day. Who was the beneficiary of Trump’s generosity? Wisconsin Club for Growth.
