Was illegal spying on Trump campaign more extensive than has been reported?

We know that Carter Page was spied on illegally since the FISA warrant was obtained using data which contrary to what the FBI said hadn't been verified.

But there may also be at least 3 other people who were also spied on according to Democrat Jackson Lee.  In questioning Loretta Lynch Lee said:

“I want to talk about the spring, summer, and autumn of 2016,” she said. “Carter Page, at the time, was suspected of being a Russian asset; George Papadopoulos had told the Australian ambassador that Russians had Hillary Clinton emails; Paul Manafort had been named Trump campaign manager; Michael Flynn was Trump’s chief national security adviser and foreign policy adviser. One thing that all of these persons had in common was that each was the subject of a FISA court investigation.”

Lynch didn't correct Lee and a senior DOJ lawyer said that Lynch shouldn't answer the question because it might relate to classified information.  That's revealing because the existence of a FISA warrant is classified.

What makes this very troubling is that under a FISA warrant the FBI can get the communications not only of the target but of everyone who the target talks to and everyone anyone who the target talks to talks to.  So for example if General Flynn talked to Trump, which was likely, then the FBI could collect all of Trumps communications.  Even worse due to the two hop rule they could collect all the communications of anyone who Trump communicated with.

That means that the FBI would have access to all of the internal planning of the Trump campaign and be able to feed that information to Hillary's campaign.

That's how the coup worked. Democrats weaponized the entire US intelligence community to help Hillary win the presidency.
