But it was released shortly after The Washington Post reported - citing unnamed United States officials familiar with the matter - that the business dealings of President Donald Trump's son-in-law, Jared Kushner, are being investigated by Justice Department special counsel Robert Mueller, who has been investigating Russian meddling in the 2016 election and the Trump administration's potential ties to Russia. A day later, Mr Rosenstein appointed Mr Mueller, who was at the helm of the Federal Bureau of Investigation during the September 11 attacks, as special counsel.
With news reports that the Special Counsel investigating election interference in 2016 by Russian Federation is looking at possible obstruction of justice by President Donald Trump, Mr. Trump expressed frustration Thursday at the prospect of that review, again taking to Twitter to denounce the probe as a "witch hunt", and complaining that Hillary Clinton should be the subject of a Russia-related investigation, not him. In a special hearing, last week, Comey told the Senate Intelligence Committee he believes Trump fired him because he resisted presidential requests to drop the Russian Federation investigation, especially as it pertained to Flynn, the former national security adviser.
Rosenstein took over the investigation after Attorney General Jeff Sessions recused himself because he was a Trump campaign surrogate.
Brand ran the Office of Legal Policy under President George W. Bush.
Since Rosenstein recommended the firing, he could be a witness in the case and ethically obligated to recuse himself. "As the deputy attorney general has said numerous times, if there comes a point when he needs to recuse, he will", Justice Department spokesman Ian Prior said in a statement.
ABC said Rosenstein told Associate Attorney General Rachel Brand she would have authority over the probe if he were to step aside. Boente is serving as the acting head of the Justice Department's national security division.
"You begin to wonder if it is going to be a domino effect here where it is just one person after another", said Andrew Graham, a longtime Maryland defense lawyer who worked with Rosenstein.
Sen. Dianne Feinstein, D-Calif., the ranking Democrat on the Senate Judiciary Committee, said Friday that she is "increasingly concerned" that Trump will try to fire Rosenstein and Mueller.
It is an option he has apparently considered in the recent past.
It was a memo written by Rosenstein that was originally used by the White House as justification for Comey's firing.
