There I believe he was referring specifically to the breaking story that Trump's descriptions of leaked Hillary emails were fed to him by Russian propagandists, a story with little basis in fact.

It may be a story with little proof and mostly conjecture, but we don't know if it has little basis in fact, or not. There is plenty of circumstantial but fairly damning evidence linking the Trump campaign to Russia.

Like the rational 'fact' that Trump is a Russian agent. Please.

Nobody is claiming that he is a Russian agent. At most, they are claiming that he is rhetorically pro-Russian, perhaps because of admiration for Putin's leadership style, perhaps because of hopes for future deals in Russia in case the 'running for President' thing doesn't work out.

No one claimed that. They are just repeating the fact that he praises Putin more than Obama.

Repeating words that directly come out of his mouth isn't bias.
