This week on Matter of Fact, Soledad O’Brien goes to Capitol to talk with Arizona Senator Jeff Flake, President Trump’s toughest Republican critic, about what he hopes to hear in Trump’s first State of the Union Address. Flake says that while Trump’s rhetoric may inspire his base to win national elections, ultimately the President could make it harder for Republicans to win important local races. Then, Houston Mayor Sylvester Turner joins Soledad in studio to talk about recovery efforts in his city following Hurricane Harvey in the fall. His message to Washington? Don’t leave us behind. Plus, is social media helpful or harmful to democracy? Soledad O’Brien sits down with Harvard professor Cass Sunstein to discuss how personalizing your news feed can make you more susceptible to fake news and drive extremism.
