Both men made speeches to signal their exit/entry from the White House and Obama/Trump respectively both provided notable moments.
Trump refusing to take a question from CNN on the 'golden showers' intelligence report and the lack of a response from the media there and then to support a colleague was disappointing.
Obama, well, he's had eight years and not speaking as an American, I don't really see he's delivered the hope and change he said he would but post-Presidency, he'll be more outspoken on topics which he might have felt restricted to speak about whilst in office.
