What advice can Obama's speechwriter give Donald Trump?
President Trump delivers his first address to Congress on Tuesday.
The White House will be hoping he can reframe his turbulent opening 40 days, but what can we expect? And how will this speech compare to those of his predecessor, Barack Obama?
Former director of speechwriting for President Obama, Cody Keenan, explains on the Today programme the importance of Obama's rhetoric, suggesting this is a chance for Trump "to do a reset".
