Companies walk away from host

Walmart and a book distributor distanced themselves from Tavis Smiley on Thursday after PBS said an investigation found “troubling allegations’’ of sexual misconduct by the radio and TV host.

The moves came a day after PBS said it was suspending Smiley following an independent investigation by a law firm. PBS said the firm 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 has denied any wrongdoing.

Walmart, which had been a sponsor of Smiley’s talk show and an upcoming touring theatrical show, cut ties with him.

“We take these issues very seriously and are troubled by the recent allegations,’’ the retail giant said in a statement. “As a result, we are suspending our relationship with Mr. Smiley, pending the outcome of the PBS investigation.’’

Hay House, which distributes the Smiley Books imprint, said all Smiley projects were “on hold’’ pending an internal review. Smiley had planned in September to release “Leading by Listening: Connecting through Conversation to Transform Your Relationships and Your Business.’’

Smiley responded to the allegations on Facebook, saying PBS “overreacted’’ and calling it “a rush to judgment.’’ He said he has never harassed anyone and claimed one relationship the network uncovered was consensual.
