Gerald Walpin said claims that he was "confused" and "disoriented" are politically motivated.Gerald Walpin, the federal inspector general fired by President Obama last summer as he was pressing his probe of Sacramento Mayor Kevin Johnson, has lost his bid to win his job back. A federal judge in Washington, D.C., dismissed a lawsuit Walpin filed in July seeking reinstatement as inspector general for the Corporation for National and Community Service, which oversees the AmeriCorps program. Walpin had claimed the White House notified him June 10, 2009, that he had one hour to resign or be fired, and in his suit he said he deserved to be reinstated because Obama could not fire him without first giving Congress 30 days notice. The administration countered that the president sent Congress notice on June 11, 2009, of his plans to fire Walpin "effective 30 days from today" because he had lost confidence in him.
