The following is part of a very revealing article by Julia Edwards Ainsley at Reuters.com:
The Trump administration is exploring whether it can use an obscure ethics rule to undermine the special counsel investigation into ties between President Donald Trump's campaign team and Russia, two people familiar with White House thinking said on Friday.
Trump has said that Deputy Attorney General Rod Rosenstein's hiring of former FBI Director Robert Mueller as special counsel to lead the investigation "hurts our country terribly."
Within hours of Mueller's appointment on Wednesday, the White House began reviewing the Code of Federal Regulations, which restricts newly hired government lawyers from investigating their prior law firm’s clients for one year after their hiring, the sources said.
An executive order signed by Trump in January extended that period to two years.
Mueller's former law firm, WilmerHale, represents Trump's son-in-law Jared Kushner, who met with a Russian bank executive in December, and the president's former campaign manager Paul Manafort, who is a subject of a federal investigation.
Legal experts said the ethics rule can be waived by the Justice Department, which appointed Mueller. He did not represent Kushner or Manafort directly at his former law firm.
If the department did not grant a waiver, Mueller would be barred from investigating Kushner or Manafort, and this could greatly diminish the scope of the probe, experts said.
The Justice Department is already reviewing Mueller's background as well as any potential conflicts of interest, said department spokeswoman Sarah Isgur Flores.
Even if the Justice Department granted a waiver, the White House would consider using the ethics rule to create doubt about Mueller's ability to do his job fairly, the sources said. Administration legal advisers have been asked to determine if there is a basis for this.
Under this strategy, the sources said the administration would raise the issue in press conferences and public statements.
Moreover, the White House has not ruled out the possibility of using the rule to challenge Mueller’s findings in court, should the investigation lead to prosecution.
But the administration is now mainly focused on placing a cloud over his reputation for independence, according to the sources, who spoke on the condition of anonymity.
