About a week after Comey was sacked last month, however, Rosenstein appointed former FBI Director Mueller as a special counsel at the Justice Department to oversee the federal investigation into Russia's efforts to meddle in the 2016 us election, according to CBS News.
Justice Department officials did not provide further context for the statement, but it came within hours after The Washington Post reported that the special counsel's investigation had expanded to include questions about Mr. Kushner's business dealings.
As Bob Mueller, the special investigator now heading the FBI's probe into allegations of Russian election meddling, filled out his legal team and prepared to begin interviews, Trump erupted furiously for a second consecutive day.
Mueller is said to be investigating whether Trump obstructed the course of justice in the probe into Russian interference in the U.S. elections.
The Republican president has repeatedly complained about the probe, calling it a witch hunt and saying Democrats can not accept his election victory.More news: Spieth stabilizes in final round at US Open
The order by the general counsel for the transition team casts a wide net on documents that could shed light on ties between Trump's presidential campaign and representatives of Russia's government.
Pence hired Richard Cullen, chairman of law firm McGuireWoods, to help him respond to inquiries from Mueller, a spokesman said.
Regardless of the outcome, the spectre of Mr Mueller examining the possibility of obstruction of justice appeared to be a new blow to Mr Trump, whose first five months in office have been clouded by the federal and congressional probes into the Russian Federation issue.
Comey said the notes contain his recollections that Trump asked for his loyalty when they met for a January dinner and then urged him during a private meeting in the Oval Office two weeks later to drop an investigation into former National Security Adviser Michael Flynn.
