President Barack Obama plans to fire the inspector general who investigates AmeriCorps and other national service programs amid a controversy between the IG and Sacramento Mayor Kevin Johnson, who is an Obama supporter and former Phx. Suns NBA basketball star.

The IG, Gerald Walpin, was criticized by the U.S. attorney in Sacramento for the way he handled an investigation of Johnson and his nonprofit group, which received hundreds of thousands of dollars in federal grants from the Corporation for National Community Service. The corporation runs the AmeriCorps program.

On Thursday, Obama said in a letter to Congress that he had lost confidence in Walpin. Neither the president nor deputy White House press secretary Josh Earnest would give details.
