"But a continuing attorney-client relationship between the attorney general and a private lawyer could signal they expect additional perilous legal questions-including from Robert Mueller III's special counsel investigation", the article says.
Cooper, a partner with his own firm, Cooper & Kirk, would not say when he was retained by Sessions or whether he is representing Sessions in the special counsel's investigation into Trump and Russian Federation.
Cooper was recently under consideration to be solicitor general, and he also reportedly advised Sessions prior to his testimony before the Senate intelligence committee last week.
Attorney General Jeff Sessions has hired D.C. litigator Charles Cooper, CNBC has confirmed.
In late May, the White House's Russian Federation scandal reached the point at which Donald Trump found it necessary to lawyer up, hiring his own outside counsel to represent the president's personal interests.
Sarah Isgur Flores, a Justice Department spokeswoman, described Cooper as "the attorney general's longtime friend and counsel".
Cooper, 65, served in the Justice Department during President Ronald Reagan's administration and returned to private practice in 1988, according to his biography on the website of his law firm. President Trump (and his own personal lawyer), Vice President Mike Pence, and Trump's son-in-law-turned-senior advisor Jared Kushner have each hired lawyers of his own.
Sessions recused himself from the Russia investigation in early March, shortly after news reports surfaced of his previously undisclosed contacts with Russian Ambassador Sergei Kislyak.
Cooper even assisted Sessions during his confirmation hearing in January.
Sessions vehemently denied any claims of collusion or improper meetings when he testified before the Senate Intelligence Committee, which is conducting its own Russian Federation investigation.
Sessions testified before a Senate panel last week that the suggestion he colluded with Russians is an " appalling and detestable lie".
