Chicago buddy: President Obama walking into the Oval Office with Valerie Jarrett in July 2010 (Photo: AFP/GETTY)

I wondered yesterday whether Robert Gibbs jumped or was pushed and noted that President Barack Obama’s words indicated that it was “not an entirely voluntary departure”.

It’s being reported by John King on CNN right now that Gibbs wanted to be a presidential counsellor – something he’s been putting about for quite a while – but William Daley, the new chief of staff, nixed this because he believed that too many cooks would spoil the presidential broth. So that’s why Gibbs is out.

Additionally, King reports that Valerie Jarrett, whose sole qualification to being a senior counsellor seems to be that she’s a long-time Chicago buddy of Barack and Michelle Obama, will have her wings clipped. Daley, not Jarrett, will be the person speaking to the business community.

It’s no secret that Rahm Emanuel, a Daley protege, clashed with Jarrett. Or that David Plouffe, about to join the White House, was often at odds with her when he was the 2008 Obama campaign manager. Obama is nothing if not ruthless. He dropped Jane Dystel, the agent who approached him to write “Dreams from my Father”, and has previously cut loose long-time advisers. One aide described him as “the most unsentimental man I’ve ever met”.

So the next question is: with Gibbs and David Axelrod gone, how much longer will Valerie Jarrett last?
