Firing Line With Margaret Hoover

Guest: Michael Moore. Filmmaker Michael Moore discusses the 2020 presidential race. Moore, who correctly predicted Trump's win in 2016, now says the Democrat could win the popular vote by an even greater margin and still lose. He explains why he supports Sanders over Warren, and suggests that they team up at the end of the primaries. He also discusses his documentaries and his public apology to Iran's ayatollah.
