While Donald Trump's official title right now is "president-elect," former Democratic presidential candidate Bernie Sanders has just referred to Trump by a different title.

"Tweeter in Chief."

Sanders took to Twitter Friday to respond to Trump's Thursday tweet concerning a need for the U.S. to expand its nuclear program.

Sanders' stance is that the government should seek to reduce the number of nuclear weapons.
