The woman serving as the foreperson of the jury that voted to convict President Donald Trump's friend Roger Stone is an activist who has been vocally opposed to the president for some time, including posting several social media messages that include calling Trump a racist.

The foreperson, Tomeka Hart, also donated $100 to Sen. Kamala Harris' presidential campaign on Nov. 10, just days before the jury she led found Stone guilty on Nov. 15 of all seven counts charging him with witness tampering and lying to Congress about his pursuit of hacked emails damaging to Hillary Clinton's 2016 election bid, according to Federal Election Commission records.

Hart admitted in a Facebook post, confirmed with her by both CNN and The Daily Memphian, that she had been the foreperson in Stone's case. She said she was coming forward to support the four prosecutors who stepped down after their recommendation that Stone be sentenced to 7-9 years in prison was rejected by the Department of Justice.

In her Facebook post, she added that she "kept my silence for months. Initially, it was for my safety."

Hart, a former Memphis City Schools Board president and a failed candidate for Congress, is also an activist who has taken part in several anti-Trump rallies and protests. She also donated to Julian Castro's campaign in June, July, and August, according to the FEC.

She now lives in the Washington, D.C., area, where she works as a senior program officer at the Bill & Melinda Gates Foundation, reports The Daily Memphian.
