Comey was never asked directly: was Trump or the campaign wiretapped? The closest question is: did Obama have Trump wiretapped.
The hearing is not an investigation, it’s a psy-op.
I was reading about FISA the other day. Apparently the FISA has to be renewed every 30 days (on the average). So every 30 days would have been a new FISA, or, an extension by the same judge who (we hope) would have insisted on seeing justification for an extension. Exceeding the original 30 days without a judge’s extension or a new FISA is a YuGE no-no.
Now we need to know which judge signed the original FISA and whether that judge granted extensions and why or why not.
