Juror 1261, we now know, was Tomeka Hart. Her identity would have remained publicly unknown except for a public statement she made after the Department of Justice (DOJ) rescinded its initial sentencing recommendation for Trump confidant Roger Stone. In the midst of the firestorm of allegations of political interference, Hart disclosed that she was the foreperson on the Stone jury and gave a full-throated defense of the trial prosecutors: "It pains me to see the DOJ now interfere with the hard work of the prosecutors." 

That statement led many people to Google her name, and what they found was a litany of postings not only hostile to President Trump and his administration but also specifically commenting on Stone and his arrest — before she ever appeared for jury duty.
