When did he say he was gifting all profits from foreign ventures to the US Treasury? Last I read about it, his pledge only related to profits from foreign governments for his hotels and similar businesses. The WaPo addressed the shortcomings of that pledge in [1].

Since it is a pledge, it also supposes that his word has any value. Anyone who looked at his business or charity dealings knows that his promises are worthless.
