Giuliani calls for "trial by combat" at Ellipse rally

At the Jan. 6 Ellipse rally, former New York City Mayor Rudy Giuliani tells the crowd "we will have a trial by combat" to overturn the election results. The phrase is a reference to "Game of Thrones" but is interpreted by supporters as a call to violence. Giuliani helped lead Trump's post-election legal challenges and spread false claims of election fraud.
