And here are a couple of interesting things not mentioned in the biography:

Priebus' Law Firm Got Clients Stimulus Funds

Priebus is a partner for the law firm Michael Best & Friedrich LLP in Milwaukee, Wisconsin. In February 2009, his firm announced the creation of a 'Stimulus Legislation Team', of which Priebus was listed as a member.

One of the client alerts co-authored by Priebus describes the team's role as such:

…The Michael Best Stimulus and Economic Recovery Team is prepared to assist you in understanding the implications and in developing and implementing a strategy to secure the benefits of this unprecedented legislation. Specifically, we will assist you to identify opportunities, prepare appropriate proposals and make targeted contacts to secure funds.

Priebus’s Law Firm Says Health Reform Is Constitutional, Touts Benefits Of Reform

Despite his heated anti-Obama attacks, Priebus makes a living at a law firm far more comfortable with the policies of President Obama. Priebus works as a partner at the Milwaukee law firm Michael Best & Friedrich LLP. Over the summer, the firm created a series of presentations to explain health reform to its clients and to pitch the firm's services for employers looking to comply with new health reform regulations. In one presentation, John Barlament, a colleague to Priebus at the firm, said that a health reform repeal is not only unlikely, but that the lawsuits brought by Republican Party allies to declare the law unconstitutional probably have no merit. Referring to the controversy over the individual mandate, Barlament explained that the commerce clause of the constitution "gives Congress authority to act on his legislation":

"Don't hold your breath," Barlament advised employers hoping the Affordable Care Act will be repealed. A number of political and business groups have called for repeal or significant revisions, but Barlament said there is nothing on the "near horizon."Lawsuits filed to block the case are unlikely to succeed because the commerce clause of the U.S. Constitution gives Congress authority to act on this legislation.

Presentations from Priebus's law firm also tout health reform benefits routinely ignored by right-wing partisans, like generous subsidies to small businesses, vastly expanding health insurance coverage in America, closing the Medicare Part D donut hole, and the end to egregious insurance company abuses (ending the program of capping benefits, ending "rescissions," ending discrimination based on pre-existing conditions).
