Idk anon, we have this statement from Barr on Nov. 14, 2017 re a Clinton investigation -
To the extent that there may be legitimate questions about Mrs. Clinton or Mr. Comey, however, the credibility of any investigation presumably would be called into question should one be authorized by Mr. Sessions or his deputy, Rod J. Rosenstein, because of the way it came about under pressure from Mr. Trump.
Of 10 former attorneys general contacted Tuesday, only one responded to a question about what they would do in Mr. Sessions’s situation.
“There is nothing inherently wrong about a president calling for an investigation,” said William P. Barr, who ran the Justice Department under President George Bush. “Although an investigation shouldn’t be launched just because a president wants it, the ultimate question is whether the matter warrants investigation.”
Mr. Barr said he sees more basis for investigating the uranium deal than any supposed collusion between Mr. Trump and Russia. “To the extent it is not pursuing these matters, the department is abdicating its responsibility,” he said.
Mr. Trump promised last year that if elected, he would instruct his attorney general to appoint a special prosecutor to investigate Mrs. Clinton. But he backed off that shortly after the election, saying, “I don’t want to hurt the Clintons.”
