Reuters reports that the Trump administration is exploring use of a little-used ethics rule against the special counsel investigation into the Trump campaigns ties to Russia.

From Reuters:

“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.”
