House Speaker Nancy Pelosi continues to refuse calls for impeachment proceedings to begin, despite the speaker stating she believes that Donald Trump has been involved in a criminal cover-up. Joy Reid and her panel discuss how the Democratic base appears to be increasingly alienated by House Democrats refusing to impeach the president, and what their logic might be. Then: Donald Trump has stated that he would apparently be open to opposition research offered to his 2020 campaign from a foreign source, although he later walked back that statement. Joy and her panel discuss the view that the president merely making this statement could impact the 2020 presidential election. Plus: Many Republican members of Congress sought to ensure to the public that they would contact U.S. intelligence authorities if they were offered information on an opponent by a foreign government or entity. Joy and her panel discuss whether Republican leaders will hold Trump accountable for apparently stating he would accept this type of information. And: Sen. Cory Booker, 2020 Democratic presidential candidate, tells Joy Reid he has changed his view on starting impeachment proceedings. Booker also tells AM JOY why he believes he is the best candidate to lead America and the Democratic party now. All this and more in this Saturday edition of AM JOY on MSNBC.Learn more about your ad choices. Visit megaphone.fm/adchoices
