From the March 17 edition of MSNBC's All In with Chris Hayes:
CHRIS HAYES (HOST): Again, there was no evidence for any of this. But it was now an allegation from the most powerful person in the world, the president of the United States, so it couldn't just be written off as a right-wing fantasy. As White House press secretary Sean Spicer unsuccessfully sought to placate reporters' demands for proof, congressional investigations got under way -- though eventually, pretty much every single last major player outside the White House said there was nothing to back the president up.
With the White House flailing, Fox News Channel judicial analyst Andrew Napolitano, who has dabbled in the past with 9/11 trutherism, came forward Monday with a theory of his own.
That utterly explosive claim also likely would have been lost to the right wing fever swamps but for the fact that Sean Spicer amazingly took to the White House briefing room yesterday to read Napolitano's claim verbatim to reporters.
