Schubert suggested his advocacy for conservative causes -- opposing abortion rights and same-sex marriage -- was hindering Schubert Flint Public Affairs' work with corporate clients.
"My conservative ideology and my faith have been major guiding forces in my decision to work on some important but controversial issues, including life and marriage," he said in a statement. "But the firm has become much bigger than me personally. I don't want my work on social issues to continue to overshadow the people who work for me, or the clients we serve. ...
"The reality is that it's very difficult for a public affairs professional to serve both corporate clients and work on the conservative side of social issues that challenge popular culture. Schubert said in a statement. "I've chosen to try to make a difference fighting for families, faith and the principles of the American founding, endowed by God, that gave rise to this exceptional nation of ours. I'm excited about the next chapter in my career."
Schubert was back in the news this year with the release of "Question One -- The Battle for Same-Sex Marriage in America," a documentary about his work on the Maine ballot measure to repeal a same-sex marriage law passed by the Legislature in 2009.
Schubert said his new company -- Mission: Public Affairs LLC -- will work on national "conservative and social issues."
Jeff Flint, meanwhile, will take over as president of the firm and "lead a restructuring and rebranding" to "focus the company exclusively on serving corporate, governmental, nonprofit and trade association clients, according to the announcement.
