IRT Ronin006:
1. your first link reports on FISA court orders related to Russian banks, not Trump campaign headquarters
2. your second link reports on FISA court orders against members of Trump's campaign, not Trump campaign headquarters
3. your third reports on FISA court orders against members of Trump's campaign, not Trump campaign headquarters

It's reasonable to suspect that the Trump operatives who were the subject of FISA warrants were the Russian-connected sleaze bags Paul Manafort, Carter Page, Michael Flynn and Roger Stone, who ran and/or were consultants for the Trump campaign, but the doesn't mean that Trump headquarters were wiretapped.
