US President Donald Trump refused to apologise for a video posted on his social media account, depicting former President Barack Obama and his wife as apes. The post has now been deleted. The sole black Republican senator Tim Scott said it was the most racist thing he'd seen come from the White House. Trump said the post was meant to expose voter fraud. Laurie Laird is a commentator on US politics and explained how the short-term impact of the post may be limited but there could be more complications at the mid-term elections for the president. #trump #us #midterm
