Deals with the Republicans in Congress whose painstakingly crafted compromises he tries to bring crashing down on a whim? Or did you mean his attempts to strike deals with the Democrats, that one time with the 'Chuck and Nancy' thing?

You know exactly what I'm talking about, so this reply was pretty absurd. Below link to an article I happened to read today covering the same point, just in case it helps you focus on the point.
