Michael Cohen's opening statement., page-3

"Questions have been raised about whether I know of direct evidence that
Mr. Trump or his campaign colluded with Russia. I do not"

As Cohen was alleged to have met with Kremlin official in Prague, according to the dodgy dossier, either Cohen is still covering for President Trump, unlikely, or the most potentially verifiable claim in the dossier is utter garbage.

Not the most sound basis for a FISA warrant to run surveillance on a rival Presidential campaign.
