They mean Fox News. They just shortened it because they were so excited. Sounds like she is going to be supoenaed to testify before an Senate Health Committee of some sort, and that Fox News is breaking the story. So if Greer starves her to death, he would be killing an official Senate witness. Also, I think that Federal Law Enforcement could take her into protective custody as a witness. Mind you, I was not watching Fox at the time. But that is what I think they are saying.
good strategy if that is indeed the way it plays out.
