Probably too much to list here, of the giving that is publicly known. For years, every year I've heard of some large donation King has given to fund some public good in Maine, some millions to build a public swimming pool, millions to the university, millions to a library, building a little league stadium, fixing up YMCAs, giving scholarships, etc. And he doesn't want the facilities he funded to be named after him either.
I don't agree with his politics, which are well-known if you'd heard his public statements, and I don't like that he also gives to liberal causes. But nobody can doubt his generosity towards his fellow Maine residents.
So this King guy is a millionaire that has not done anything other than spend his money for some good things without wanting his name attached. I guess he must be one of those “silver spoon” folks who inherited daddies money and haven’t had to work in life, thus doesn’t know what it is to work, thus is a liberal. gotcha, another non-working liberal layabout who doesn’t do anything productive in life.
