Do not invite  St. Louis  county spokesman Mac Scott and KMOX news honcho John Butler to the same soiree.  Scott and Butler have been exchanging angry calls over the radio station’s use of unnamed sources to assert that federal authorities are investigating contract irregularities in involving current senior employees of county government.  Scott denies  it, noting that a former employee’s records were subpoenaed in an income tax investigation involving a home in another state.  Butler insists he has first hand sources. Somebody is wrong.
