The IT tech who set up the private email server through which Hillary Clinton conducted official government business while she was secretary of state, including top secret communications, will be deposed in a lawsuit.

But the video interview Wednesday in a case brought by Judicial Watch likely won't yield much, if any, information.

It's because Bryan Pagliano has said he will plead the Fifth and not answer questions, even though he's already been granted an immunity deal.

Judicial Watch is questioning a number of Hillary Clinton aides and may even seek to put the presumptive Democratic nominee for president under oath, too, as it tries to get information about the controversial employment status of top aide Huma Abedin.

U.S District Court Judge Emmett Sullivan said Pagliano’s deposition can be videoed, and while the video itself will be kept secret for now, the transcript of the answers will be made public.

Judicial Watch, which already has deposed several other Clinton aides, said several more also still are scheduled. Abedin will be questioned June 28 and Patrick Kennedy to appear June 29.

The court granted Judicial Watch discovery rights in its lawsuit seeking details of the system, which may have been used to evade public records laws.

Lawyers for Pagliano already have affirmed he will refuse to answer, claiming the right under the Fifth Amendment not to incriminate himself.

WND has reported several times on the suspicious circumstances that have developed in the case.

For example, the emails from Pagliano while he worked with Clinton now cannot be found. The State Department denied it could find any of Pagliano's emails, even though he would have been required to turn over any official communications from his work account before he left his government position.

The overall issue of the security of the email system is important because Clinton would have agreed when she was appointed to the post to properly maintain security on information critical to the United States. If she mishandled or was careless with it, criminal charges could result.

Her critics have been busy speculating in recent weeks what could happen to her, including one political pundit who noted her first act in office, should she win the 2016 election, could be to pardon herself.

Pagliano set up the server in Clinton's home in Chappaqua, New York, while she was secretary of state.

ABC reported Raj Shah, an RNC spokesman, said: "Such records might shed light on his role in setting up Clinton's server, and why he was granted immunity by the FBI. But it seems that his emails were either destroyed or never turned over, adding yet another layer to the secrecy surrounding his role."

Abedin is a former deputy chief of staff for Clinton. But she also was working in the private sector, for the Clinton Foundation as well as another organization run by a friend of former president Bill Clinton, while being paid by the government.

The lawsuit had been closed down but was revived when the private email server was discovered.

In response to the FOIA, the agency's official records were searched regarding Abedin, but it turned out Clinton's private server had not been searched.

"Judicial Watch raises significant questions in its Motion for Discovery about whether the State Department processed documents in good faith in response to Judicial Watch's FOIA request. Judicial Watch is therefore entitled to limited discovery," the judge wrote in reopening the investigation.

In a separate FOIA lawsuit, regarding Clinton's actions surrounding the Benghazi terror attack, federal Judge Royce Lamberth previously ruled Judicial Watch can conduct discovery of Clinton and her top aides regarding their email.

Sullivan found that the question remained: "Did the State Department, in good faith, conduct a search reasonably calculated to uncover all relevant documents."

The ruling said: "The circumstances surrounding approval of Mrs. Clinton's use of clintonemail.com for official government business, as well as the manner in which it was operated, are issues that need to be explored in discovery to enable the court to resolve, as a matter of law, the adequacy of the State Department's search of relevant records in response to Judicial Watch's FOIA request."

When another Clinton aide, Cheryl Mills, was questioned under oath, she had a series of memory lapses – stating "I don't recall" 40 times and "I don't know" another 182.
