On Wednesday Steve Colbert told his audience to "brace themselves" because President Donald Trump's "tweetnado" was coming.

President Trump went on a Twitter rant about the Special Counsel Robert Mueller's investigation and demanded that Attorney General Jeff Session un-recuse himself.

By tweeting this he could have incriminated himself on social media and provided more evidence of obstruction of Justice.

"Donald Trump is telling his attorney general to shut down the investigation of Donald Trump," Colbert said. "Rudy should tell him that just because he is doing it in public, it's still obstruction of justice. Just like public urination is still urination."
