He later sort of implied that he read the FISA before signing it and based on what he knew at the time, that it was appropriate.
My thought as I listened was to wonder if the warrant he signed was the same as what went to the FISA court.
I also am wondering if, when they confidently testify that they didn’t believe political bias impacted the ultimate decision, it is because the motive was actually different - ie, a conspiracy to cover up wrongdoing. That’s a completely different motive and they keep declining to produce documents and information regarding “investigations” that are ongoing.
