Former U.S. Attorney General Eric Holder joins CBS News' Vladimir Duthiers to explain why he wrote his new book, "Our Unfinished March: The Violent Past and Imperiled Future of the Vote-A History, a Crisis, a Plan." He shares why he remains optimistic about America's future while writing a call to action. In his book "Our Unfinished March," Holder outlines proposals such adding Puerto Rico and D.C. as states, eliminating the electoral college, taking the politics out of redistricting and reforming the Supreme Court. Holder, the chairman of the National Democratic Redistricting Committee, responds to the reversal of Roe v. Wade and the House committee's investigation into the January 6th attack on the Capitol.
