Trump Backtracks on Questioning Russia's Interference in the US Presidential Election

President Trump has said he accepts that Russia tried to interfere in the 2016 US elections -- directly contradicting his assertion made in Helsinki after his summit with Vladimir Putin; today marks the centenary of Nelson Mandela's birth. We hear from one of his granddaughter's about the hundreds of poignant letters he wrote during the 27 years he was a political prisoner; and Yemen's exiled president, Abd Rabbu Mansur Hadi, has acknowledged that the Saudi-led military intervention to restore him to power was taking much longer than he had hoped.
