Barack Obama and Donald Trump campaign for midterm candidates

10:07

Former President Barack Obama is on the campaign trail for Democrats – going after President Trump and trying to do his part to usher in a “blue wave” in the midterms. Will it be effective? Also, Bob Woodward’s book, “Fear,” and an anonymous op-ed in the “New York Times” have sparked upheaval in the White House. Lanhee Chen, research fellow at the Hoover Institution, former adviser to the Rubio campaign and former chief policy adviser to the Romney campaign, Jonathan Alter, MSNBC political analyst and columnist for "The Daily Beast," Ali Vitali, NBC news political reporter, and Kurtis Lee, the Los Angeles Times national correspondent, join MSNBC’s Richard Lui for the discussion.
