The former "Kelly File" and "Megyn Kelly Today" host also was the first to interview Ashley Bianco, who was fired by CBS in November for reportedly leaking a hot mic clip of ABC host Amy Robach. In a tearful interview, Bianco staunchly denied leaking the clip.

In the hot mic clip, Robach claims that she had a story about Jeffrey Epstein three years ago, but that the network quashed it.

Kelly posted the interview on her Instagram page and on YouTube.

"Megyn Kelly Presents" also posted a response to the movie "Bombshell," which focuses on sexual harassment allegations against former Fox News chairman and CEO Roger Ailes. The video has generated nearly 1.3 million views.

Charlize Theron's portrayal of Kelly in the movie earned an Oscar nomination for best actress.

Theron later called Kelly's reaction to the movie "validating."
