Tennessee Republican Sen. Marsha Blackburn said during an interview with Fox News that the biggest reason Democrats like Sen. Adam Schiff of California and others “fear” Kash Patel to lead the FBI is because he knows their roles in perpetuating the “Russian collusion” hoax during President Donald Trump’s first term.“I think, too they are very fearful of Kash Patel because Kash Patel knows what Adam Schiff and some of the others did with Russia collusion, and they know that he — knows the dirt on them, if you will, and I think they’re fearful of what he’s going to do and what he’s going to reveal and what he’s going to make known to the American people,” Blackburn told guest host Charlie Hurt on “Fox & Friends” Sunday.
