What it does
A plain-language summary is coming. Here is the official summary from the Congressional Research Service:

It also makes the site a part of the African American Civil Rights Network established under the African American Civil Rights Network Act of 2017. In addition, the act directs the Department of the Interior to conduct a special resource study of the site to evaluate its national significance and determine the suitability and feasibility of designating the site as a national historic landmark.
How Congress voted
