Trump's 'word salad' history of Russia invading Afghanistan is evidence he's someone's 'puppet': Trump biographer

Appearing on MSNBC to discuss Donald Trump's history-challenged description of Russia invading Afghanistan, a biographer of the president said that it was obvious he was being fed false information about a country he knows nothing about.


Speaking with AM Joy host Joy Reid, Tim O'Brien -- who wrote "TrumpNation" jumped all over the president, describing him as clueless about the region and its history.

"We have to wonder why these talking points that are clearly Kremlin talking points end up in Donald Trump's mouth," O'Brien began. "He's probably the most wildly ill-informed and illiterate president we have had in the Oval Office and he would be hard-pressed to find Afghanistan on a map."

"What's disturbing is when you move past the word salad of it, this sort of tragicomic aspect of Trump when he does this strange performance art is that it's a national security problem," he warned.

"You have someone who is the commander in chief and has lots of power to execute policy on behalf of the country overseas -- he really doesn't know what he's talking about. And when he does speak, it looks like he's the puppet of other people," he cautioned.
