The WaPo article on this claims that Trump said, actually it said pledged, that he would only play with world leaders and others while making deals. I watched just about every Trump rally and I do not recall such "pledge". It will be funny to see this listed in a column of "pledges" not kept. WaPo will have to stretch to find any such unmet pledges.
WaPo's comments are such lopsided Trump-hating statements. Yikes! These leftists are in for a big surprise.
