Wow...talk about incompetence. The Hill makes it sound like the CIA told the FBI "hey, Page is working for us"...and in fact Page had helped with an investigation in 2013...Stop lying. They stated predicate for opening such an investigation is so low that basically "thinking" something is enough to do it. That's why Horowitz gave them a pass when they pleaded to him that they were just incompetent instead of biased with the framing.

This investigation was rife with missteps, framing of Trump associates, and misconduct. While they admitted the evidence was flimsy and they needed very little to justify starting it (Horowitz had no choice but to accept that) when it became obvious that Russian collusion was a fraud the whole thing should have been shelved. It wasn't....but instead the misconduct and framing continued under the guise that it was sheer "incompetence" instead of bias.
Facts matter.
Who was framed? What misconduct? It is not obvious that collusion was a fraud. Trump did benefit from Russian efforts.
People make mistakes. Does that make them incompetent? Trump makes mistakes...on a daily basis. He double crossed our allies (the Kurds). He has been more positive about Putin than our European allies...he has demoralized our military and our intelligence services. Does that make him incompetent? One of his mistakes alone, no. Taken as a whole, how can you deny that he's a blowhard windbag and certainly unable to do the job.
