Donna Brazile sent a message to President Trump after he ripped the Democratic National Committee for its arrangement with Hillary Clinton’s campaign that’s leading to more people calling the Democratic presidential primary rigged against Sen. Bernie Sanders.

“I think he needs to look at his own house before he tries to clean up someone else’s house,” she said on ABC’s “This Week.”

Trump’s campaign is the focus of multiple investigations in Congress as well as special counsel Robert Mueller, who handed down indictments and announced one conviction in his investigation into Russian meddling in the 2016 election. Part of that investigation is answering the question of if there was any collusion between Trump’s campaign and the Russian government.

Brazile, meanwhile, sent shockwaves through the political world with an excerpt of her book that unveiled the unusual arrangement between the DNC and the Clinton campaign.

The Clinton campaign essentially took over the DNC in August 2015, during which time Clinton was running against Sanders and multiple other Democrats for the party’s nomination. Experts have said that arrangement, which allowed the Clinton campaign to have veto power over expenditures from the DNC, may have tipped the primary to Clinton.
