OTTAWA - U2 lead singer and activist Bono says working with a Trump administration in the fight against extreme poverty and preventable diseases would be his biggest challenge -- by far.

Bono has worked closely with Republicans in the past, including George W. Bush, but he says the party's current nominee Donald Trump falls into a special category.

The Irish rocker tells The Canadian Press that he has enormous respect for a party with a membership that includes some of his best friends.

Bono says he has lots of sympathy for Trump supporters whose concerns such as America's shrinking middle class cannot be ignored -- but he's not sure the businessman is actually a Republican.

He says the jingoism and hate-filled speech that comes with the Trump campaign is unhelpful -- and he has yet to figure out how he would deal with it.

Bono is co-founder of ONE Campaign, an international organization dedicated to ending extreme poverty and preventable diseases, especially in Africa.
