Trump BUSTED in bogus ballroom claim by Obama era secret

Rachel Maddow explains how a secret bomb shelter installed under the White House during the Obama administration undercuts Donald Trump's legal claim that he needs his ballroom constructed because it will include a necessary bomb shelter for the White House. Rachel is joined by Greg Werkheiser, co-founder of Cultural Heritage Partners, to discuss a coalition of organizations working to protect Washington cultural and historic landmarks from Trump's reckless vanity projects.
