"Trump's ouster of AG Sessions and replacing him with Trump toady Matthew Whitaker is clearly a move to interfere with the investigation of Russia's attack on the 2016 election". Whitaker is Sessions' former chief of staff.
Mr Trump tweeted shortly after the resignation was announced, naming a temporary replacement of Sessions. He looked close to tears as he was applauded by the staff on his way out of the justice department building on Wednesday night.
Experts say, however, that any investigation into the role foreign countries play in domestic politics must delve down financial rabbit holes.
"We've won the majority in the House, so, the days of just looking the other way are over", the California Democrat told MSNBC's "Morning Joe".
The next month, Whitaker wrote an op-ed posted on CNN's website in which he argued that Mueller's investigation appeared to be going too far and may constitute a "witch hunt", echoing one of Trump's favorite descriptions to criticize and discredit the probe.
As Sessions' deputy, Rod Rosenstein has been the authority over Mueller's probe, but multiple media outlets are reporting that he has officially been removed from oversight of the investigation. The Trump administration is going to be investigated over Russian Federation, taxes, voter ID laws, any aspect of this White House the Left hates was going to be put under the microscope now that Democrats have retaken the House. Whitaker also said the probe should not extend to the finances of Trump, his family or their business.
As for the reports on Trump, if Whitaker suppresses them, the House Judiciary Committee could subpoena them and make them public.
"Interference with the special counsel's investigation would cause a constitutional crisis and undermine the rule of law", Adam Schiff said.
As part of Whitaker's new role as the head official at the Justice Department, he will oversee the Russian Federation probe and the agency's other federal investigations, including the NY prosecutors' look into the finances of Trump and his former aides.
Protests are scheduled to start Thursday at 5pm local time.
Stefan Holt also reports on President Trump's tense post-midterm press conference where he targeted CNN's Jim Acosta; results in the gubernatorial election in CT; and an odd request in the trial for Mexican drug lord Joaquin "El Chapo" Guzman.
Sessions, a 71-year-old former Republican senator from Alabama, was the first senator to endorse Trump's insurgent presidential campaign.
Sessions recused himself from managing the investigation because of his own past involvement in the Trump campaign.
As reason for his recusal, Sessions cited news reports of two undisclosed meetings he had with Sergey Kislyak, then Russia's ambassador to Washington.
Recent acting and permanent attorneys general have been longtime government lawyers or high-ranking politicians with more experience navigating Washington than Whitaker. In an interview past year with a conservative talk radio host, Whitaker said there was "no collusion" between Trump's campaign and Russian Federation, a key question being examined by Mueller.
