I'm attempting to make a list of World Leaders who have mentioned bitcoin either directly by saying the word 'bitcoin' or indirectly by saying "blockchain technology" or "Financial Technology" or something along those lines. Does anyone know of a list?

So far I have:

David Cameron, Prime Minister of the United Kingdom:
