"I want Comey to come to our committee".
Asked whether Lynch provided improper political cover for Clinton, Feinstein said: "I can't answer that", but a "separate investigation" is worthwhile to find out.
Sen. Feinstein, who serves on both the Judiciary Committee and Intelligence Committee, said the obstruction of justice case might hinge on the words from Comey's private moments with President Trump after the room was cleared of Attorney General Jeff Sessions, who employs the FBI Director appointed by the office of the president and, in this case, fired by the president.
"I would have a queasy feeling, too, though, to be candid with you", Feinstein told CNN host Brianna Keilar on "State of the Union." . He told the Senate Intelligence Committee that such a request would match the wording of Clinton's campaign.
Dianne Feinstein has called on the head of the Senate Judiciary Committee to investigate the issues related to obstruction of justice in the firing of FBI Director James Comey and the probe into Russian meddling in the 2016 Presidential election, using "subpoena authority if necessary".More news: Tottering Theresa May names new UK Cabinet as critics circle
"I know on two separate occasions he has told members of the House and the Senate the main reason that he jumped into the election a year ago and took over the job of the Attorney General was because he believed there were emails between the Democratic National Committee and the Department of Justice that compromised the Department of Justice", Graham said.
Lynch, a President Obama nominee, ultimately had to distance herself from the FBI probe after meeting with former President Bill Clinton on a tarmac in Phoenix during the height of the election campaign and email investigation.
Comey said on CBS program "Face The Nation" he wanted to know if it was true that Comey was spurred by that document to make his July announcement that he would not recommend charges to the Justice Department. "This is a very big deal".
When exactly did Lynch ask Comey to downplay the Clinton investigation? That question should certainly be at the top of Feinstein's list if she manages to get Lynch to testify.
