Trump insider on 'thin ice' after 'boxing' in president as crisis mounts

Add MSNBC contributor John Heilemann to the list of Washington, D.C. insiders who believe that there is a growing schism between Donald Trump and his top intel adviser as the threat of a major war in the Middle East seems imminent.

Appearing on MSNBC's "Morning Joe," Heilemann was asked by a report from Politico that Trump is "incensed" with DNI Tulsi Gabbard after she posted a video online that warned of a doomsday scenario of nuclear war that caught the Trump administration off-guard.
