Trump's morning Twitter targets: NYC suspect, Elizabeth Warren and his own Justice Department

President Trump is currently on board Air Force One en route to Honolulu, but he's still tweeting after an active morning on his favorite website — even by his prolific standards — that saw POTUS push the Department of Justice to investigate the Democratic Party over the "rigged" 2016 primaries.

Why it matters: The Department of Justice is an independent entity that remains free of the whims of the president. As Special Counsel Robert Mueller's Russia investigation gains steam against Trump campaign surrogates, Trump would benefit from staying out of Justice's way in order to avoid any hints of impropriety.
