Hakeem Jeffries 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 Hakeem Jeffries announces that he 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 Jeffries endorses another candidate for Democratic Nominee, this market will resolve to "No". The resolution source for this market will be official information from Jeffries or one of their representatives.
