But the Russian Federation cloud threatening to engulf the President is far more than political.
The focus on Rosenstein sharpened Friday because the President attacked the deputy attorney general in a tweet, blaming him for what he terms a "witch hunt".
Rosenstein, the deputy attorney general, had written a memo castigating James Comey before Trump dismissed the Federal Bureau of Investigation director - a memo that the White House at first said was critical to the decision, before Trump suggested it was irrelevant because his mind was already made up.
"I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director!" But she also surely knows that Robert Bork was the Department of Justice official who ultimately fired Watergate investigator Archibald Cox in President Richard Nixon's Saturday night massacre.
He added: "Having refused to admit his errors, the director can not be expected to implement the necessary corrective actions".
Rosenstein brought up the possibility of recusing himself during a meeting with the Justice Department's third-in-command - behind Sessions and Rosenstein - Associate Attorney General Rachel Brand, ABC News reported. Only six lawmakers voted no. The memo included stinging criticism of the FBI director's handling of the investigation of Hillary Clinton's email.
Mr Robert Mueller, the special counsel named by the department to investigate the Russian Federation matter, is now examining whether Mr Trump or others sought to obstruct the probe, a person familiar with the inquiry said on Thursday.
Rosenstein addressed dealing with political considerations around investigations during an interview with ABC2 News in Baltimore earlier this year, arguing that "it is not difficult" for him to separate politics and the way he prosecutes cases. And in the Justice Department, that is what we do on a daily basis, that is how are trained.

Only a month ago, Rosenstein, a veteran of the Justice Department, received the President's praise.
"The president is the president of the United States, so they are considered official statements of the president of the United States", Spicer said.
But Rosenstein's rise through Justice has not been without pitfalls.
But she lacks any background in criminal law, which would be important if she is charged with taking over the Russian investigation, according to Lawfare.
"We will enforce the embargo", the President said.
In addition, Trump has also publicly criticized Rosenstein.
The poll also found that there is a growing level of concern regarding the contact that Trump's affiliates had with Russian officials over the course of previous year.
It was unclear whether the president's comment confirming he was under investigation was based on direct knowledge or media reports that Mueller is examining whether the president obstructed justice by firing Comey.
