(CNN) - Sarah Palin is losing a key member of her inner circle.
Lawyer Tom Van Flein is departing Palin's world to work for incoming Arizona Rep. Paul Gosar, according to Gosar's office. The Anchorage Daily News first reported the story Monday.
"I am pleased to have Tom Van Flein, with his experience and background, help me in D.C. with my District issues and the issues facing our country," said Gosar. "As one of my trusted advisers, I look forward to working with him in Washington and ensuring that we listen to the American people and work to uphold the principles that make this country great."
Van Flein is among only a handful of advisers with regular access to Palin, having served as both a legal, political, and media adviser to the former Alaska governor as she has navigated the political waters since her debut on the national stage in 2008. His is certain to leave a big hole in Palin's circle, especially as the former vice presidential nominee considers gearing up for a presidential election bid.
"Rep. Gosar is getting a wise, experienced and principled hand that will help him hit the ground running. Along with millions of Americans, I will be watching the new freshman class shake up D.C." Palin said in a statement.
Gosar was among the Republicans Palin endorsed ahead of the midterm elections.
"The mid-term elections represent a tectonic shift," said Van Flein. "I want to work with Rep. Gosar because he is committed to Arizona, and he is committed to making government more efficient, and our country more independent from its reliance on foreign energy and natural resources."
