Sorry, but Obama was fully within his authority and used it because of the Republican Congress' refusal to do anything on immigration reform.  (Couldn't give Obama any wins, as Mitch McConnell publically stated his job was to make Obama fail.)  As for liberals pulling out the race card?  Seriously?  Trump rode into office on the race card.  He's an avowed supporter of white supremacists - which, a reasonable person would surmise, makes him one too.
