This was the Grand Jury that indicted Fauci aide David Morens who is presumably spilling his guts to the U.S. Attorney as part of a (so far) sealed plea agreement.
The mention was just a short bit in a long New York Times article on September 5:
...Prosecutors in Maryland also recently demanded the testimony before a federal grand jury of a former staff member at EcoHealth Alliance, a defunct nonprofit that the Trump White House has said used N.I.H. funding to facilitate “dangerous” research at the Wuhan lab where the administration believes the pandemic started....
The rest of the article reads a bit like a magicians misdirection: "Look here, don't look there."
Whether or not that impression is correct, it appears the next focus of the Grand Jury's attention will be Peter Daszak and EcoHealth Alliance.
