(CNN) What we know: This is the week that Michael Cohen officially declared war on Donald Trump. As recently as May, Trump lawyer Rudy Giuliani was on TV touting Cohen as "an honest, honorable lawyer." And, he could pardon Cohen even before Cohen is charged with anything. Seen through the lens of a potential pardon, Cohen could be using this week to signal to Trump that he's not bluffing. Cohen's motives should come into sharper focus in the coming weeks, depending on what we hear from Trump, Mueller or both.
