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.  

But he said when "you actually get into the details of the Steele dossier, the specific allegations, we have not seen the evidence to support them, and, in fact, there's good grounds to think that some of the more sensational allegations will never be proven and are likely false."
