Democrat Cal Cunningham's campaign to represent North Carolina in the U.S. Senate has been rocked in recent days by the revelation of an extramarital affair, but none of the major news networks have addressed the controversy on-air.

On Friday, Cunningham's campaign confirmed that a series of text messages suggesting a relationship between the married Cunningham and Arlene Guzman Todd, a public relations strategist from California, were authentic. The texts had been published by a conservative website, NationalFile.com.

On Monday, Cunningham pulled out of a town hall event hours after Guzman Todd told the Associated Press that she and Cunningham had an "intimate encounter" in July.  In text messages to her friend, Guzman Todd said she was intimate with Cunningham in his home, which she later characterized as “weird.”

In another exchange, Guzman Todd indicated that she was frustrated by the limited attention that he showed her, writing: “I’m just going to send to his opponent his naked photos. That will teach him.”

The three broadcast networks, ABC, CBS, and NBC, also skipped the Democrat's controversy in both their morning and evening news programs.

In a statement, Guzman Todd apologized for the “pain and embarrassment, and disrespect I’ve caused to my immediate family, loved ones, and everyone affected by this situation.”

“A few months back, I displayed a lapse in judgment by engaging in a relationship with Cal Cunningham during a period of marital separation,” Guzman Todd said. “The relationship spanned several months and consisted primarily of a series of text exchanges and an in-person encounter." She did not elaborate, but her text messages described the intimacy.
