About 300 lawyers, their clients, potential clients and political types filled a swank private club in Milwaukee on Tuesday night to hear incoming White House chief of staff Reince Priebus discuss what an attendee said he called “the most exhilarating and thrilling moment of his life:” Donald Trump’s victory on election night.

The three-hour gala was thrown by Michael Best & Friedrich, whose partnership Priebus will formally leave at the end of the month. He joined the Milwaukee firm after graduating law school in 1998 and became a “partner on leave” in 2011 when he won an election to become chair of the Republican National Committee.
