(JNS.org) U.S. Secretary of Defense Chuck Hagel, a past source of controversy due to his statements about Israel, announced his resignation on Monday.

The New York Times reported that President Barack Obama decided to push for Hagel’s resignation “as a recognition that the threat from the Islamic State would require different kind[s] of skills than those that Mr. Hagel was brought on to employ.” While the newspaper explained that Hagel “came in to manage the Afghanistan combat withdrawal and the shrinking Pentagon budget in the era of budget sequestration,” it quoted an Obama administration official as saying that the remaining two years of the president’s term “will demand a different kind of focus.”

A former Republican U.S. senator from Nebraska, Hagel came under heavy criticism from some Jewish organizations and from legislators on both sides of the political spectrum for his record on Israel during a historically tight battle for confirmation in late 2012 and early 2013. Among Hagel’s most controversial past comments was that “the Jewish lobby intimidates a lot of people” in Washington, DC, a quote he gave former Middle East peace negotiator Aaron David Miller for the book 2008 book The Much Too Promised Land.
