President Trump accused the Democratic National Committee of “collusion” after former DNC head Donna Brazile revealed "proof" that the Hillary Clinton's campaign had taken over the DNC.

In a pair of tweets Thursday evening, the president also continued a recent slate of criticism against his Justice Department.

“Donna Brazile just stated the DNC RIGGED the system to illegally steal the Primary from Bernie Sanders. Bought and paid for by Crooked H....,” Trump said in a series of tweets Thursday. “....This is real collusion and dishonesty. Major violation of Campaign Finance Laws and Money Laundering - where is our Justice Department?”

Trump's campaign, meanwhile, is being examined by a federal team and a number of congressional probes for possible collusion with the Russians during the 2016 election. Trump has called the inquiry a "witch hunt."

Brazile, the former interim DNC chairwoman, said in a book excerpt obtained by Politico, that the Clinton campaign gained control of the DNC's finances and operations to defeat Sen. Bernie Sanders, I-Vt., in the 2016 Democratic primary.

Brazile cited "proof" on an agreement she discovered between two Clinton campaign funds and the DNC, in which money would be exchanged for control over DNC finances and strategy.

Trump critique of the Justice Department follows a swipe he took on Wednesday when he said during a Cabinet meeting that the U.S. justice system is "a joke" and "a laughingstock.” The comments were made as Trump endorsed harsher punishment for terror suspects, referring to the man suspected to be behind the deadly New York City terrorist attack this week.
