I hope those people in the audience took note of how he blew her off and refused to address what she was saying.
I bet that the vast majority of people in that audience never heard of the "two hop" power of the FISA warrant. Almost always even Republicans say "spied on Carter Page" which, while wrong to do, is nothing like spying on every person he communicated with and then spied on every person that circle communicated with. Republicans are so stupid.
A FISA warrant was never intended to be used on an American citizen, much less a presidential candidate and then President.
