He said his focus will remain on redistricting and battling to make sure the House is not made up of members from “gerrymandered districts.”

"Though I will not run for president in 2020, I will continue to fight for the future of our country through the National Democratic Redistricting Committee and its affiliates," Holder, who served as the nation's top law enforcement officer under former President Obama, wrote in a Washington Post op-ed.

"I will do everything I can to ensure that the next Democratic president is not hobbled by a House of Representatives pulled to the extremes by members from gerrymandered districts."

Holder was the head of the Justice Department between 2009 and 2015. He currently serves as the chairman of the National Democratic Redistricting Committee, a group focusing on voting rights and redistricting issues.
