Donald Trump didn’t mince words Friday when he responded to a reporter’s question about his thoughts on the priorities at the Department of Justice.

“I’m really not involved with the Justice Department. I’d like to let it run itself, but honestly, they should be looking at the Democrats, they should be looking at Podesta and all of that dishonesty, they should be looking at a lot of things,” Trump told reporters at Joint Base Andrews ahead of a trip to Asia Friday.

“And a lot of people are disappointed in the Justice Department, including me.”

Trump’s comments follow revelations published in a book by Donna Brazile, former head of the Democratic National Committee, that explain exactly how Hillary Clinton rigged the Democratic primary in her favor. Politico published an excerpt from Brazile’s book on Thursday.

The issue is the latest in a long line of questionable conduct by Democrats that’s been seemingly ignored by the Justice Department, including emails involving Clinton campaign chairman John Podesta exposed by WikiLeaks in 2016, a “Uranium One” deal approved while Clinton was Secretary of State that granted Russians greater control over uranium operations in the U.S., a deal that was allegedly linked to shady dealings at the Clinton Foundation. Trump has also highlighted reports that Clinton’s campaign helped fund opposition research during the campaign that was allegedly gathered by Russian intelligence to produce a “dirty dossier.”

Trump’s remarks come just days after former Trump campaign chairman Paul Manafort and business associate Rick Gates faced indictments on Monday as part of special counsel Robert Mueller’s ongoing, open-ended investigation into allegations of collusion between the Trump campaign and Russia. The indictments, however, center on consulting work the two did for a Ukrainian politician years before Manafort joined the Trump campaign and don’t appear to be linked to the president.

Trump has repeatedly branded Mueller’s investigation as a “witch hunt,” and he reiterated Friday that his campaign did not coordinate with the Russians to influence the election.

“All I can tell you is this: There was no collusion, there was no nothing. It’s a disgrace, frankly, that they continue,” Trump said at Joint Base Andrews. “You ought to look at Hillary Clinton, and you ought to look at the new book that was just put out by Donna Brazile, where she basically bought the DNC and she stole the election from (Democratic challenger) Bernie (Sanders). So that’s what you ought to take a look at.”

Trump elaborated on the problems at the Justice Department with The Larry O’Conner Show.

“You know, the saddest thing is, because I am the President of the United States, I am not supposed to be involved with the Justice Department. I’m not supposed to be involved with the FBI. I’m not supposed to be doing the kind of things I would love to be doing and I am very frustrated by it,” he said.

“I look at what’s happening with the Justice Department, why aren’t they going after Hillary Clinton with her emails and with her dossier, and the kind of money… I don’t know, is it possible that they paid $12.4 million for the dossier…which is total phony, fake, fraud and how is it used? It’s very discouraging to me.”

At Joint Base Andrews, a reporter asked the president whether he would consider firing U.S. Attorney General Jeff Sessions if the Justice Department doesn’t free up more agents to investigate Democrats, Fox News reports.

“I don’t know,” Trump replied.
