Bernie Sanders On 2020 Race; Jeremy Hobson's Grandmother On Brexit

Sen. Bernie Sanders is running for president on a platform pushing for "Medicare for All," the Green New Deal, tuition-free public colleges, legalizing marijuana and increasing taxes on wealthy Americans. We speak to him about his campaign thus far. Also, host Jeremy Hobson is reporting from London on Brexit. And he visits his 93-year-old grandmother, who supports leaving the EU, to hear how she and their extended family feel about the referendum.
