(CNN) — After five years away from his collegiate job and seven months away from his family, the U.S. ambassador to Russia says it's time to come home.
Michael McFaul, the U.S. ambassador to Russia since late 2011, announced Tuesday that he'll step down from his post this month, soon after the Winter Olympics in the southern Russian resort town of Sochi.
McFaul took a leave from Stanford University, where he is a professor of political science, in 2009 to serve on the National Security Council before U.S. President Barack Obama appointed him to his current post.
On his online journal, McFaul said Tuesday that his wife and two sons moved back to California last summer because his oldest son wanted to be home for the last few years of high school.
"We tried to make a 9,000 kilometer commute work for our family. But after seven months of separation, I simply need to be with my family again," McFaul wrote.
CNN first learned of McFaul's planned departure on Twitter.
