Having helped re-elect President Barack Obama with his unrestricted super PAC Priorities USA Action, former White House official Bill Burton will now join the public affairs firm Global Strategy Group.

“Bill has played a major role in two successful presidential elections, advised and represented the President of the United States, and has a deep understanding of the communications and political landscapes in Washington,” the firm’s CEO, Jon Silvan, said in a statement.

Burton will be executive vice president and managing director in Global Strategy Group’s Washington office. Before running Priorities USA Action as senior strategist, Burton was deputy press secretary at the White House. Burton’s previous posts include communications director at the Democratic Congressional Campaign Committee and communications adviser to several Capitol Hill Democrats.

Having initially kept unrestricted outside groups at arm’s length, Obama reversed course and embraced super PACs last February. Priorities USA Action got off to a slow start but eventually raised $76 million, according to the Center for Responsive Politics, making it the top-grossing super PAC backing Democrats.
