Warnock calls on Democrats to investigate those who redrew maps

He says Congress should see if "racial animus" was behind redistricting efforts.

Senator Raphael Warnock, D-Ga, is calling for Democrats to investigate officials who he says have "manipulated their maps to silence the voices of Black voters," as soon as they flip the House or Senate in the midterms.

In the plan, first reviewed by ABC News, Warnock said, "Here is what Democrats must do as soon as we regain power: investigate craven politicians, ban partisan gerrymandering, stop billionaires from buying our elections, expand our democracy and guarantee the right to vote for all Americans."

Warnock has not ruled out a run for the White House in 2028. That possibility comes as roughly a third of the Congressional Black Caucus risks losing its seats before 2028, with GOP-led Southern legislatures redrawing maps after the Supreme Court's Louisiana v. Callais ruling gutted Section 2 of the Voting Rights Act.

In Louisiana, where Black residents make up roughly one-third of the population, a federal court had found that a post-2020 congressional map with only one majority-Black district likely diluted Black voting power. The legislature responded by drawing a second majority-Black district as courts had required in similar circumstances.

Justice Samuel Alito, who authored the Supreme Court opinion, which said that states only violate the Voting Rights Act when "evidence supports a strong inference that the State intentionally drew its districts to afford minority voters less opportunity because of their race."

Republicans have argued that they are redrawing congressional maps to comply with the Supreme Court or to remedy unfairly-drawn districts, and that the districts that could be changed may still elect Black representatives to Congress.

Calling for officials who he says have engaged in gerrymandering to decimate minority voices is a position Warnock hasn't called for until now, and he said in a phone interview with ABC News that the Callais decision was an "inflection point" for him to do so.

"A Democratic majority in either chamber must immediately investigate these officials, including through Congressional hearings, document requests, depositions, testimony, and, if necessary, subpoenas," Warnock's plan states. "We must analyze their statements, actions, and contributions to determine if there is any evidence that they broke any laws in their race to gerrymander and silence Black voices."

Asked whether Democrats who've engaged in partisan gerrymandering -- in California, for example -- should face investigation, Warnock said that the state's redis
