Richard Arnold: US Correspondent on the division in the Democrats on Biden's insistence on running

As world leaders descend on Washington DC for NATO talks, domestic politics remains front of mind in the US, UK, and France.  Donald Trump is hitting the campaign trail in Florida and Pennsylvania just days before he's due to unveil a running mate at next week's Republican National Convention.  Joe Biden is continuing to fend off questions over his re-election bid.  US Correspondent Richard Arnold told Andrew Dickens the Democrats are divided, Steve Cohen saying they’re not on the same page, “not even the same book”.  He said that world leaders will be making their own assessments of Biden’s strengths as he hosts the NATO conference.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
