Gerald Walpin, a former Inspector General with the Corporation for National and Community Service which oversees AmeriCorps said in an interview with Byron York of The Examiner that his firing was politically motivated.

Yes, we knew that. We knew that Walpin's investigation into the misuse of AmeriCorps funds by Sacramento Mayor Dennis Johnson was the proximate cause of his firing. What we didn't know, as York points out, was how blatant it was:

The White House's decision to fire AmeriCorps inspector general Gerald Walpin came amid politically-charged tensions inside the Corporation for National and Community Service, the organization that runs AmeriCorps.  Top executives at the Corporation, Walpin explained in an hour-long interview Saturday, were unhappy with his investigation into the misuse of AmeriCorps funds by Kevin Johnson, the former NBA star who is now mayor of Sacramento, California and a prominent supporter of President Obama. Walpin's investigation also sparked conflict with the acting U.S. attorney in Sacramento amid fears that the probe -- which could have resulted in Johnson being barred from ever winning another federal grant -- might stand in the way of the city receiving its part of billions of dollars in federal stimulus money.  After weeks of standoff, Walpin, whose position as inspector general is supposed to be protected from influence by political appointees and the White House, was fired.

Walpin learned his fate Wednesday night.  He was driving to an event in upstate New York when he received a call from Norman Eisen, the Special Counsel to the President for Ethics and Government Reform.  "He said, 'Mr. Walpin, the president wants me to tell you that he really appreciates your service, but it's time to move on,'" Walpin recalls.  "Eisen said, 'You can either resign, or I'll tell you that we'll have to terminate you.'"
