US House of Representatives paralysed

Without a speaker no business can be conducted. Has this action damaged the Republican party? We hear from one of the rebels and one of the moderates.

Also on the programme: we hear from the first indigenous person to be elected to the role of premier of a province in Canada. Wab Kinew is from the Ashinaabe First Nation; and we also hear from one of the winners of this year's Nobel Prize for Chemistry, Professor Moungi Bawendi.
