Republicans in the Senate are urging President Donald Trump to nominate a new permanent attorney general amid rising concern over the safety of special counsel Robert Mueller's investigation, Politico reports.
Napolitano added that if Whitaker's appointment is found to be illicit, it would likely make his decisions "null and void" - which would be problematic if they greatly affect the nation, like a potential constraint of Special Counsel Bob Mueller.
The president later tweeted that Mr Mueller and "his gang of Democrat thugs" were destroying people, and blamed social media tech giants for unfavourable coverage towards his administration and the Republicans.
Republican Senator Jeff Flake and Democrat Chris Coons had said they would push the measure after Trump fired Attorney General Jeff Sessions and tossed out more than a century of precedent to name Sessions chief of staff Matt Whitaker as acting attorney general on November 7.
The Senate is expected to hold a vote that aims to protect the investigation, which has ensnared a number of Trump campaign officials.

Trump last week ousted Attorney General Jeff Sessions, whom Trump had long attacked for removing himself from oversight of the Mueller probe, adhering to Justice Department guidelines requiring officials to recuse themselves from involvement in cases to avoid conflicts of interests.
In 2016, USA intelligence agencies concluded that Russian Federation had used a state-authorised campaign of cyber attacks and fake news stories planted on social media in an attempt to turn the election against Democrat candidate Hillary Clinton.
Mueller has won convictions or secured guilty pleas from several Trump campaign figures, who are cooperating with Mueller's investigators while awaiting sentencing.
