You are referring, at several removes, to the interview Isikoff gave to Ziegler earlier this month ...
Michael Isikoff, the chief investigative correspondent for Yahoo News, said Saturday during an interview on conservative commentator John Ziegler's "Free Speech Broadcasting" podcast that "Steele was clearly onto something" in his probe into the campaign's Russian connection but evidence has not surfaced to support some of his specific assertions.
Steele was correct to suspect "that there was a major Kremlin effort to interfere in our elections, that they were trying to help Trump's campaign, and that there were multiple contacts between various Russian figures close to the government and various people in the Trump campaign," Isikoff said.

Please point out where Isikoff made ANY of the "admissions" you claimed:
"the left's disloyalty and collusion with foreign powers"
"Democrats colluding with Russia"
"all the key pillars are likely false"
"Democrats invented the entire thing"
