POTOMAC, MARYLAND - JUNE 19: Maryland Democratic candidate for U.S. Senate and Prince George's County Executive Angela Alsobrooks (2nd-R) watches a kids dance competition during the Scotland Juneteenth Heritage Festival Parade at Cabin John Regional Park on June 19, 2024 in Potomac, Maryland. Alsobrooks is running against Republican Senate candidate and former Governor of Maryland Larry Hogan. The first federal holiday to be established in almost 40 years, the Juneteenth National Independence Day marks the day in 1865 when the last enslaved Black Americans in Galveston, Texas, learned that they had been freed two years earlier by the Emancipation Proclamation.
