The US Department of Justice (DOJ) has announced that the associate deputy attorney general (AG) of the US, their third highest ranking official, will be departing from the DOJ.
Ms Brand, who became the associate attorney general in May 2017, has not given any reason for her departure.
She was next in line behind to oversee the special counsel investigating Russia's meddling in the 2016 presidential election after Mr. Sessions recused himself.
Sessions applauded Brand for her service to the DOJ, calling her "a lawyer's lawyer".
But the White House denied that there would be any changes made at the Justice Department later that evening. But Brand was next in line to take over if Rosenstein recused himself, or was removed and not immediately replaced. The attacks have escalated in recent weeks as Republicans in Congress have criticized the handling by the Justice Department, FBI and the Federal Intelligence Surveillance Court of warrants for surveillance of a Trump campaign advisor, Carter Page, who had ties to Russian Federation.
"Rachel has shown real leadership over many important divisions at the department", Sessions said in a statement Friday night in which he congratulated Brand. That job would now fall to the solicitor general, Noel Francisco.
Unlike her two immediate superiors, Sessions and Rosenstein, Brand has largely avoided the public ire of President Donald Trump, who has not criticized her conduct in his not-uncommon pronouncements about conduct at DOJ.
The US justice department's No 3 official is leaving for the top legal job at Walmart, it has emerged.
The department said Brand will be leaving her post in the coming weeks. She will be responsible for the organization's Legal, Global Ethics and Compliance and Global Investigation, Security, Aviation and Travel departments, along with her role as corporate secretary.
Brand has one of the department's more politically challenging jobs, managing the lawyers who litigate civil issues, including Trump's travel ban as well as civil rights, environmental and antitrust cases. The 702 program allows the collection of foreign intelligence from non-Americans located outside the United States.
Faulkner began the interview by asking whether Trump - who told reporters Friday that the allegations were "very sad" while reminding his audience that Porter "says he's innocent" - deserves "credit" for addressing the situation head on.
