PBS has suspended the "Tavis Smiley" show following an investigation into sexual misconduct allegations against its host and producer, Tavis Smiley.

An investigation by an outside law firm found "credible allegations" that Smiley engaged in sexual relationships with subordinates, according to Variety.

"Effective today, PBS has indefinitely suspended distribution of 'Tavis Smiley,' produced by TS Media, an independent production company. PBS engaged an outside law firm to conduct an investigation immediately after learning of troubling allegations regarding Mr. Smiley," a PBS spokesperson said in an email to the Washington Examiner on Wednesday.

"This investigation included interviews with witnesses as well as with Mr. Smiley. The inquiry uncovered multiple, credible allegations of conduct that is inconsistent with the values and standards of PBS, and the totality of this information led to today’s decision.”

The witnesses, according to Variety, included men and women who said Smiley's behavior created a threatening environment and they feared retaliation. Some witnesses believed their employment was tied to a sexual relationship with the host.

Smiley's program began airing in 2004.

Smiley is not the only prominent television host to face sexual misconduct allegations in recent weeks. PBS and CBS host Charlie Rose, as well as "Today" show host Matt Lauer, were both fired after complaints about inappropriate sexual behavior in the workplace.
