How many African Americans served in government at the national level?

in the explanation is my answer

Explanation:

Many blacks view political representation as a potential catalyst for increased racial equality, according to a 2016 Pew Research Center survey. Roughly four-in-ten black adults (38%) said that working to get more black people elected to office would be a very effective tactic for groups striving to help blacks achieve equality. Whites were less likely to view this as an effective way to bring about increased racial equality (24% said it would be very effective).

Data from the past 50 years reveal the upward yet uneven trajectory of black political leadership in America. In 1965, there were no blacks in the U.S. Senate, nor were there any black governors. And only six members of the House of Representatives were black. As of 2019, there is greater representation in some areas – 52 House members are black, putting the share of black House members (12%) on par with the share of blacks in the U.S. population overall for the first time in history. But in other areas, there has been little change (there are three black senators and no black governors).
