AOC endorses Kamala as Dem Nominee?

On July 21, Joe Biden announced he was dropping out of the presidential race, and endorsed Kamala Harris for Democratic Nominee. This market will resolve to "Yes" if Alexandria Ocasio-Cortez announces that she formally endorses Kamala Harris as Democratic Nominee for President of the United States before the Democratic Party officially nominates its candidate for the 2024 presidential election. Otherwise this market will resolve to "No". If AOC endorses another candidate for Democratic Nominee, this market will resolve to "No". The resolution source for this market will be official information from AOC or one of their representatives.
