Jon Stewart: 'I can't tell you who Clinton is'

The Daily Show host Jon Stewart spoke to Justin Webb about his directorial debut Rosewater and the upcoming 2016 presidential election.

In 2009 the Tehran-born Canadian journalist Maziar Bahari was imprisoned and tortured for 118 days in Iran.

Amongst the western media that campaigned for his release was the American satirical news programme The Daily Show, and Bahari was interviewed by its host Jon Stewart following his release.

Stewart made his first feature film Rosewater, released in the UK on May 8, based on Bahari’s story.

Justin asked Stewart about Hillary Clinton's chances in the 2016 presidential elections.

"Politicians have gotten really practiced at running for office and not so great at running other things than campaigns," he said.

"Whether or not she will emerge as someone who we believe or that we think has a clear vision for what she will actually do is absolutely the question," he added.

The UK release date of Rosewater is May 8 2015.
