The most revered job in speechwriting will be vacated when Jon Favreau leaves the White House after four years as President Obama’s chief speechwriter.

The 31-year-old Favreau is reportedly leaving the coveted post to write screenplays for Hollywood—a “well-worn path” for White House scribes, according to London’s The Telegraph. Another of Obama’s former speechwriters, Jon Lovett, is co-creator of the NBC sitcom “1600 Penn,” reports the Los Angeles Times.

Favreau began working with Obama seven years ago after interrupting him during a speech rehearsal to offer some suggestions for improvement. At the time, Obama was running for U.S. Senate. Upon his election, the first-term senator hired Favreau.

During the next seven years, Favreau has reportedly helped write some of Obama’s most poignant speeches.

Longtime Obama advisor David Axelrod told the L.A. Times: “When they're working together, it's like watching two musicians riff. Jon's stamp is on all of the great speeches, from 2005 until now.”

Favreau was also the subject of many shining media profiles, although he was not without controversy. In December 2008, one month after his boss was elected to the White House, Favreau apologized after a photo of him groping a cardboard cutout of Hillary Clinton was posted online.

Cody Keenan, part of the current White House speechwriting team, takes over as the president’s top speechwriter. He is reportedly helping Obama draft his state of the union speech, which the president will deliver on Tuesday, Feb. 12.
