Stephen Colbert, the Late Show host, played the ultimate prank on his audience as he complimented Donald Trump's speech about the Iran war. Colbert stated that the speech was "concise, intelligent" and brought the nation together with shared purpose. He also mentioned that he had yet to watch the speech because The Late Show tapes too early and had put lamb's blood around his TV so it would pass him by. The host also commented on the president's attendance at a Supreme Court hearing about birthright citizenship, which he described as "demonic" and "mobility".
