I doubt that Pelosi and Schumer were no at least cc’d on the Steel dossier and the get rid of Trump strategy from the beginnig.
they were both part of the Gang of 8 that were given briefings by both Brennen and Comey.
They knew there was a covert Op going on. And the not only let it go on, they endorsed it.
Remember the Harry Reid letter to Comey demanding information about Trump and Russia. This was directly after a briefing.
These two bags of feces remained silent. They wanted him taken down.
