In a series of tweets Sunday morning, President Donald Trump trashed the FBI and Department of Justice for not revealing to his campaign that agents were “secretly investigating" his former campaign chairman, Paul Manafort, during the 2016 election.

“As only one of two people left who could become President, why wouldn’t the FBI or Department of “Justice” have told me that they were secretly investigating Paul Manafort (on charges that were 10 years old and had been previously dropped) during my campaign?” Trump wrote in one tweet..

He then went on, writing that Manafort “came into the campaign very late and was with us for a short period of time.” The campaign “should have been told that Comey and the boys were doing a number on him, and he wouldn’t have been hired!”

Trump named Manafort head of his campaign in June 2016. Manafort stepped down in August of that year after media reports of his dealings with the Ukraine government emerged.
