The U.S. Chamber of Commerce's Dave Natonski is leaving the business lobby to head back to the Hill as Republican Rep. Aaron Schock's deputy chief of staff. It's a homecoming of sorts for Natonski who was Schock's communications director between 2009 and 2010. (It's worth noting that he was not part of the congressman's team when Schock decided to bare his ripped abs to Men's Health earlier this year.) In his new role, he'll manage the Washington office's day-to-day operations and help beef up the the communications team. He starts after the first of the year.
