Exercise his power and set the tone, as Trump is trying to create smokescreens.
The Russia investigation started in June 2016. The Carter Page FISA thing came about in October 2016. And it involved FIUR DIFFERENT JUDGES.
So, the Russia investigation had nothing to do with that FISA warrant. If anything, it was of the process of an invstigation that started months earlier.
In short: A Bust!
A Nothing Burger.
A political stunt.
