“I cannot put into adequate terms the condemnation I feel, and so many Americans feel, that this President’s fundamental transformation of this country is indeed the destruction of the American dream of being compensated based on being the best that you can be.
The concept of social justice and economic quality is truly bizarre. The President’s a bad man.

So, did Nugent sincerely apologize for calling the President of the United States a mongrel, a communist, and a gangster?
