Chief Justice Roberts is the one who gets to appoint judges to the FISA court every last one of them, judges like Rudolph Contreras, who granted a previously denied Michael Flynn FISA warrant. His appointees are the ones who swallowed whole the contentions of the Obama administration using unverified material put together by a British agent and his Russian sources to aid one political party at the expense of another.
Thanks dennisw. IOW, Roberts is an Obama judge in all but name.
In Robert's case there really isn't much difference between an Obama judge and a Bush judge...
