On its face, the contents of the Nunes memo should concern every American - before we even get into the political spin.
What the memo alleges - and we've seen nothing to refute any of this from the FBI or anyone else - is that the FBI relied on a highly partisan, unverified dossier to justify wiretapping a member of the Trump presidential campaign. It also alleges that the FBI relied on the same unverified dossier to renew the wiretap warrant twice as it was expiring. And it further alleges that the FBI knew the dossier was a bought-and-paid-for piece of political propaganda, but didn't tell this to the FISA judge whose job it was to approve or deny the wiretap warrant.
