This certainly seems like a pattern. The President first trashed Paul Ryan in that horrendous budget speech while Ryan was in the first row. Now he hammers Trump while he’s in the audience at the White House correspondents’ dinner.
The biggest question is, what the heck was Trump doing there? What good was going to come from that?
Obama certainly had his fun at Trump’s expense. Maybe The Donald had it coming. Either way, it’s not particularly presidential.
