Fox News suspended Eric Bolling, a longtime host at the network, on Saturday pending an investigation into reports that he sent lewd photographs to three female colleagues via text message.

Fox News learned about the allegations against Mr. Bolling after an inquiry from HuffPost, the network said in an emailed statement.

In an article published Friday night, HuffPost cited a dozen anonymous sources who said Mr. Bolling had “sent an unsolicited photo of male genitalia via text message to at least two colleagues at Fox Business and one colleague at Fox News.”

It said the messages had been sent several years ago and on separate occasions.

A lawyer for Mr. Bolling, Michael J. Bowe, did not immediately respond to an email seeking comment on Saturday. Mr. Bowe told HuffPost, “Mr. Bolling recalls no such inappropriate communications, does not believe he sent any such communications, and will vigorously pursue his legal remedies for any false and defamatory accusations that are made.”
