The technician, Bryan Pagliano, was granted immunity during the FBI’s investigation into the former secretary of State's server.

Republicans say the deal means Pagliano should have no fear of testifying before the committee in its investigation of Clinton’s use of the server.

“Under those circumstances, Mr. Pagliano has no fear of criminal liability preventing him from testifying before the committee,” Chairman Jason Chaffetz Jason ChaffetzThe myth of the conservative bestseller Elijah Cummings, Democratic chairman and powerful Trump critic, dies at 68 House Oversight panel demands DeVos turn over personal email records MORE (R-Utah) said Thursday during a hearing.

But Democrats say the agreement is “limited” and therefore does not protect Pagliano before the Oversight Committee.

Rep. Stephen Lynch (D-Mass.) on Thursday morning pointed to an outstanding criminal referral from Chaffetz that asked the U.S. attorney for the District of Columbia to investigate deletions from the server.

The committee on Thursday morning will vote to hold Pagliano in contempt of Congress for failing to appear before the committee under subpoena.
