Gerry Adams "£5 Billion" RHI cost gaffe - shouldn't he be across the detail? @daithimckay and @malodoherty discuss

We've been hearing for months that the RHI scandal that could cost taxpayers up to £490million. It was cited by Sinn Fein's Martin McGuinness as the main reason for his decision to resign as Deputy First Minister. So wouldn't you expect their President, his best mate, Gerry Adams, to be across such an important detail? You'll be able to have a listen to what he said on RTE radio yesterday.
