The Department of Justice pulled a last-minute maneuver to block an FBI agent allegedly involved in Big Tech’s suppression of the Hunter Biden laptop story from testifying before Congress.

The House Judiciary Committee is investigating whether Hunter Biden’s laptop was downplayed by social media companies. As part of the probe, Chairman Jim Jordan uncovered that an FBI agent involved in the saga — Elvis Chan — lied about the computer.

Chan had agreed to voluntarily appear Friday to provide the committee testimony and be represented by his personal counsel.

Agency witnesses are allowed to bring either agency counsel or personal counsel to committee interviews, but not both. The rule is set up so agency witnesses can be more candid in testimony without fear of professional retribution, according to the committee.

But two sources with direct knowledge of the situation tell DailyMail.com that DOJ derailed the testimony because agency counsel also showed up Friday morning. As a result, Chan’s interview did not take place as planned.

Now, an official subpoena is expected to be issued later Friday for Chan to appear for a transcribed interview next Thursday, Sept. 21.
