The Democratic National Convention is officially underway. The president began his long goodbye from American politics with an address to the nation in which he sought to remind Americans of his achievements in office., at times angry and visibly emotional.

And before that there was a speech from former presidential candidate Hillary Clinton, who used her time at the podium to say that it's time for Kamala Harris to break the 'glass ceiling'.

Sarah, Justin and Anthony are all together in Chicago to chat through a defining week in Kamala Harris’s bid to defeat Donald Trump to the White House.
