Accuser Says Sacramento Mayor Kevin Johnson Offered to Pay Her $1,000 a Month

The accusation is contained in a 62-page report issued by two ranking Republican congressmen investigating President Barack Obama's firing last summer of Gerald Walpin, a federal inspector general who had been investigating alleged misuse of federal grant money by Johnson and his nonprofit St. HOPE organization.

Walpin sent the findings of his probe - including the allegation that Johnson had offered the payments - to the U.S. attorney's office in Sacramento for consideration of criminal charges. The office reviewed Walpin's findings and opted instead to reach a civil settlement with Johnson.

"The facts outlined in the referral give rise to reasonable suspicions about potential hush money payments and witness tampering at a federally funded entity," the congressional report concludes. "Yet, it is unclear what, if anything, the U.S. attorney's office did to investigate these allegations."
