In a letter to GOP leaders, former Congressional Budget Office Director Douglas Holtz-Eakin on Wednesday suggested White House advisor Larry Summers “should be back at Harvard,” for sending a letter to Republicans that insists the $787 billion stimulus is creating jobs.

Summers last week wrote to House Minority Leader John Boehner, R-Ohio, in response to GOP suggestions for creating jobs that were sent to Obama. Summers’ response letter to Republicans blamed the nation’s economic problems on the Bush administration policies and credited Obama’s stimulus plan for positive economic changes.
