Darrell Issa (R-CA) joined Breitbart News Saturday on SiriusXM Patriot Channel 125 and discussed the Brexit vote with guest host Matthew Boyle, Breitbart’s Washington political editor, saying it was a “significant loss” for both President Obama and the presumptive Democratic nominee Hillary Clinton because they were behind the push for the United Kingdom (U.K.) to remain part of the European Union (EU).
