On July 13th last year a would-be assassin narrowly failed to kill Donald Trump, instead grazing the Republican candidate's right ear. Many people of faith - both on the right and left - see this narrow miss as something of a miracle, and for some evangelicals it is a sign of God's favour towards the president-elect. Roy Jenkins looks at the influence of faith groups on US politics, and the Republican party in particular, as Americans and the world look towards Donald Trump being officially declared the 47th President of the USA. For these groups, it is particularly important to have the ear of the President as they press their own agendas. Roy speaks to Professor Mark Silk, political analyst Calvin Dark, and to pro-Trump minister Pastor Mark Burns.
