Antonia Ferrier, a former staffer for Senate Majority Leader Mitch McConnell, has joined Definers Public Affairs as a partner. Ferrier was previously staff director to the Senate Republican Communications Center. Story Continued Below In an interview, Ferrier praised Definers Public Affairs as among “the best in the business.” “I wanted to work with people who were open to new ideas, different ideas, new ways to confront problems and challenges — that’s frankly what they do here at Definers,” she said, adding that after 14 years on Capitol Hill, she was ready for a new chapter and wanted to get out of her comfort zone. In reflecting on her time on the Hill, Ferrier praised McConnell’s team for getting tax reform, judges and deregulation through over the past two years. In addition to working for McConnell, which Ferrier described as “the honor and privilege of [her] life,” Ferrier was also a senior adviser and communications director to Senate Finance Committee Chairman Orrin Hatch (R-Utah) and worked for John Boehner (R-Ohio) when he was House minority leader. She also worked for Rep. Roy Blunt of Missouri when he was House Republican Whip and for Sens. Olympia Snowe (R-Maine) and Bill Frist (R-Tenn.). Definers Public Affairs was thrust into the news recently after The New York Times reported that Facebook had hired the firm to conduct opposition research on liberal financier George Soros. Facebook later cut ties with Definers.
