"I think Democrats, who are certainly emboldened by the election, will certainly say ... that there's a conflict here," Moreno told Hill.TV's Krystal Ball and Buck Sexton on "Rising." 

"I think it's grey. I think these things are often left to the officials themselves, and I think it's a rabbit hole that frankly we don't need to be going down because I think, my expectation is, he will have a similarly light touch over the Mueller investigation as Rod RosensteinRod RosensteinLewandowski says Mueller report was 'very clear' in proving 'there was no obstruction,' despite having 'never' read it Nadler's House committee holds a faux hearing in search of a false crime House Democrats seeking Sessions's testimony in impeachment probe MORE has had these 18 past months, and I don't think it's going to be an issue long-term," he continued. 

"The issue is going to be what, if anything, does Bob Mueller find? So it's the substance, I think, not the process that will ultimately be what's really important here in the long run," he said. 

Moreno's comments come less than a day after Attorney General Jeff Sessions was ousted by President Trump

The Justice Department told The Hill that Trump's pick to replace Sessions, Whitaker, will oversee Mueller's probe. 

"The Acting Attorney General is in charge of all matters under the purview of the Department of Justice," DOJ spokeswoman Sarah Isgur Flores said in a statement. 

Trump has long slammed Sessions's decision to recuse himself from the Mueller investigation, which he has called a politically motivated "witch hunt."

Democrats have said that Whitaker's previous critical comments about Mueller's probe make him unfit to oversee the investigation. 

Politico reported on Wednesday that senior House Democrats are planning to invite Mueller to testify on Capitol Hill if Trump takes action to shutter the Russia probe.
