BYRON YORK: AmeriCorps scandal figure un-invited from AmeriCorps conference. “On Thursday I reported that Kevin Johnson, former NBA star, mayor of Sacramento, California, and friend and political ally of Barack and Michelle Obama, was scheduled to speak at an AmeriCorps conference in New York at the end of this month. . . . Now comes word that Johnson will not be speaking at the conference after all. On Thursday afternoon, his picture and biographical sketch disappeared from the conference website, and today the Corporation for National and Community Service (CNCS), which oversees AmeriCorps, confirmed that Johnson will not be there.”
