Latest development of the Mueller investigation

In this article from the Onion, Robert Mueller shares one of his thoughts about Trump. According to the Onion, Mueller is shocked that Trump hasn't put an end to his investigation yet. He says that a smarter president could have ended his investigation within a month or 2 by using some kind of loophole or as Mueller puts it "if Trump just had any negotiation ability or public relations skills whatsoever, he could’ve just used good old-fashioned deal-making to shut this thing down." 

The Onion uses the satirical technique of the understatement by making what Mueller says about loopholes and deals seem totally normal but the point of the article is to make fun of the way politics work. It is saying that powerful people can just make their wrongs right by using shady loopholes that save their own skin. It is criticizing Trump for not knowing what he is doing but mostly focusing on politicians in general for using loopholes to get out situations they need to take responsibility for.
