Buchanan has been outspoken on curbing immigration, nationalising the economy, and opposing multiculturalism.
And in the second half of the show Riz speaks to Green party presidential candidate and former congresswoman Cynthia McKinney.
Her platform is far to the left of the mainstream parties, advocating "respect for each other and for the environment". She opposes the Israeli occupation of the Palestinian territories, proposes changing the Department of State into the Department of Peace, and condemns America's militarised foreign policy. She is controversial for claiming that George Bush, the US president, was involved in 9/11.Watch part one:
