Joy Reid leads this episode of The ReidOut with Ted Cruz's endorsement of Donald Trump for president--the same Trump who ridiculed the looks of his wife and accused his father of killing JFK. Cruz is just one of many Republicans, whom Joy calls "cowardly," who have signed on to Trump's authoritarian revenge tour, at the mere price of their dignity. Also in this episode, Joy examines the alarming parallels between President Biden and Lyndon Johnson as each man faced re-election, including their roles in two very unpopular conflicts. Plus, we expose the possible Supreme Court reversal of a 1984 decision that created something called the "Chevron deference," which enshrines government powers to regulate industries, as a key case is argued now before the Supreme Court. All this and more in this edition of The ReidOut on MSNBC.
