Another Politico journalist is jumping ship. This time, it’s Charles Hoskinson, who is setting sail to join The Navy Times as their Managing Editor. He has been writing the Morning Defense column. Hoskinson has a long history as a military man and reporter. He served 10 years as an officer in the Army Reserve and Guard before diving into the world of journalism. He has also served as an embedded reporter with troops in both Afghanistan and Iraq.

It’s interesting to note that Hoskinson is the third Morning Defense writer to leave in less than two years. And the seventh national security or foreign affairs writer to leave since Politico began five years ago. He’s the fourth Politico reporter to bolt so far this year. Sarah Libby, Bill Hamilton, Karen Tanabe, and now Hoskinson have all left in 2012. (We’re not even counting Ben Smith and Marin Cogan, who left late December of last year.)

We have reached out to Politico’s Editor-in-Chief, John Harris, for a comment.
