This week saw both news organizations and the Romney presidential campaign arguing over the veracity of claims made by the Obama administration about Romney's tenure at Bain Capital, the financial services company Romney co-founded. Political scientist and media critic Brendan Nyhan says that part of the problem is that the media has fallen down on the job in properly reporting this story.

Brendan Nyhan is a Dartmouth political scientist who studies why scandals break when they do. According to Nyhan, before this month's GSA fiasco, President Obama had the longest streak of scandal-free coverage of any President in recent history. Nyhan tells Bob that according to his theory, we can expect the coming months to be full of scandal coverage.
