On Thursday, Michael Cohen said he's willing to testify that President Donald Trump knew about the meeting between Jared Kushner, Donald Trump Jr., and Russian emissaries.

That revelation flies in the face of most of the administration's denials, which have ranged from refusing to admit the meeting took place to confessing that it happened -- but they merely discussed adoption.

Naturally, President Donald Trump's personal lawyer, Rudy Giuliani, was dispatched to cable news to undermine Cohen's testimony.

"Giuliani this weekend. What is the plan there?" Fox News host Shepard Smith asked Fox News Sunday host Chris Wallace.

But Wallace just burst into laughter.
