NEW YORK (AP) — PBS has suspended radio and TV host Tavis Smiley after finding what it called "troubling allegations" of sexual misconduct, making him the second high-profile star to be ousted from a network known for its high-brow, genteel programming. The Public Broadcasting Service said Wednesday an independent investigation uncovered "multiple, credible allegations of conduct that is inconsistent with the values and standards of PBS." His show's page at PBS was scrubbed on Thursday. Smiley shot back on Facebook, saying PBS "overreacted" and calling it "a rush to judgment."
