Julián Castro, Democratic presidential candidate, and former United States Secretary of Housing and Urban Development, discusses the Donald Trump administration proposing rule changes that could cause millions to lose food stamps, plus the state of the race for 2020, in conversation with Joy Reid. Plus: When the Trump House impeachment inquiry hearings resume next week, a leading Republican wants to call Rep. Adam Schiff, the chairman of the House Intelligence Committee, as his first witness. Then: Trump is headed to London this week for the 70th anniversary NATO summit, just days after the Trump administration has moved to cut U.S. funding to the alliance, which many experts say would be applauded by Vladimir Putin. Vladimir Kara-Murza, Vice President of the Free Russia Foundation, joins AM JOY to discuss. And: Sen. John Neely Kennedy made the debunked argument Sunday morning on NBC’s ‘Meet the Press’ that Ukraine was involved in interfering with the 2016 elections, a hoax promoted by Russia, the actual, sole culprit. Finally: Who are the biggest winners of the week in politics, top news, and more? Watch and weigh in—plus, AM JOY welcomes a special ‘Who Won the Week’ guest, DNC Vice Chair Michael Blake, democratic candidate for Congressional District 15 in New York State. All this and much more in this Sunday edition of AM JOY on MSNBC.
