How much did Hillary Clinton know, regarding the Trump Tower wiretaps and FISA warrants (assuming they existed)?

What we know: The first FISA request came right after former Attorney General Loretta Lynch met with Bill Clinton on the airport tarmac in Phoenix Arizona on June of 2016.

The first FISA request was denied.

A week later FBI Director James Comey exonerated Hillary Clinton from further investigation saying…

"Our judgment is that no reasonable prosecutor would bring such a case."

We also know (via various news reports) that a second FISA request was submitted in October of 2016 just before the US elections.
