WASHINGTON – Members of the Senate Judiciary Committee are pressuring Chairman Chuck Grassley to ask former Attorney General Loretta Lynch to testify before the panel on whether she interfered with the Justice Department’s investigation of Hillary Clinton’s email server.

An aide to Sen. Ted Cruz (R-Texas) told The Post on Monday that the Texas Republican wants Lynch to respond under oath to bipartisan concerns that she attempted to influence the Clinton probe – an explosive claim made by ousted FBI Director James Comey during his testimony last week.

Comey told senators that Lynch directed him to call the email probe a “matter” instead of an investigation, a move he said “confused and concerned” him.

“Cruz absolutely supports Lynch testifying before [the] Judiciary committee,” said Catherine Frazier, a spokeswoman for the Texas senator.

Two other members of the Judiciary Committee – Sens. Dianne Feinstein (D-Calif.) and Lindsey Graham (R-S.C.) – have publicly urged Grassley (R-Iowa) to summon Lynch.

“I think we need to know more about that, and there’s only one way to know about it, and that’s to have the Judiciary Committee take a look at that,” Feinstein, the committee’s ranking Democrat, said on Sunday.

The Judiciary Committee is already investigating whether Comey affected the Clinton-related investigation with his public statements about the former secretary of state’s email activity last July, as part of its investigation into the circumstances surrounding his removal by President Trump last month.

That investigation “necessarily includes [the] DOJ and FBI’s handling of both the ongoing review of Russian interference in the 2016 election and the closed Clinton-related investigation,” a spokesman for Grassley told The Post, adding that the American people “deserve to know whether improper political interference affected either case.”

The spokesman declined to say it Grassley would summon Lynch to testify.

Former Attorney General Michael Mukasey, who preceded Lynch at the Justice Department and has accused her of damaging the agency’s independence, said Congress “ought to get bottom of why the Justice Department chose not to use a grand jury” in the Clinton email case – a question he wants Lynch to answer during sworn testimony.

“Telling Comey how to talk about the work they were doing was just the tip of the iceberg,” Mukasey told The Post. “It was the symptom of possibly other influences on the [Clinton] investigation.”

A person familiar with the discussion between Lynch and Comey said the former attorney general asked Comey and other department officials during a meeting in September 2015 if they were “comfortable with using the term ‘matter’” to describe the Clinton email probe.

“No one, including the director, contested that view,” the source said.
