Pete Souza's latest Instagram lets Trump know who the real 'Rocket Man' is

If Pete Souza keeps it up with his Instagram responses to President Trump, we're going to start thinking he doesn't like the guy!

On the morning of Sept. 17, Trump referred to Kim Jong-un as "Rocket Man" in a tweet (shortly before retweeting a video in which he hits Hillary Clinton with a golf ball — it's been a big day for the president). While the taunting nickname is bizarre in the context of things American presidents have said throughout the nation's history, it's just another Sunday morning for Trump.

Souza, former Chief Official White House Photographer during the Obama Administration, responded with an Instagram of the only "Rocket Man" in President Obama's life.

There's only one Rocket Man, here meeting with President Obama in 2015.

Ah, good times.
