Biden’s 100 days: Vaccines, China, and greenhouse gases

President Joe Biden has reached his 100th day in the White House. How has he spent his 'honeymoon' period? And how is he navigating tricky relationships with Russia, China and the UK? <br /><br />Host Dermot Murnaghan speaks to Omarosa Manigault Newman, a former aide to President Trump, about Biden's stance on racial equality and his domestic popularity. Plus, Dr Leslie Vinjamuri, Director of the US and the Americas programme at Chatham House, explains how his approach to China will involve much more than trade.
