Donald Trump’s team said today that Michael Flynn Jr. — the son of Trump’s pick for national security adviser, retired Lt. Gen. Michael Flynn — was forced out of the transition efforts amid controversy over a fake news story that he pushed on Twitter.

“The younger Michael Flynn was helping his father with some administration and scheduling duties early on in the transition process,” Trump team spokesman Jason Miller said, adding that Michael Flynn Jr. is “no longer involved with the transition efforts.”

Both Michael Flynn Jr. and Michael Flynn Sr. have shared fake news stories on their twitter accounts.  One fake news story they shared related to the pizzagate conspiracy involving the Comet Ping Pong in Washington D.C.
