US President Joe Biden on Tuesday announced Vice President Kamala Harris will lead the administration’s efforts on voting rights as  he urged Congress to make June “a month of action on Capitol Hill.”

Speaking at an event in Tulsa to commemorate the 100th anniversary of the massacre, Biden also assailed recent laws restricting voting rights passed by Republican-led states. Biden said voting rights in the United States are “under assault” with an intensity he has never seen before. “It’s simply un-American.”

“I’m asking Vice President Harris to assist these efforts, to lead them among her many other responsibilities. With her leadership and your support, we’re going to overcome again. It’s going to take a hell of a lot of work,” Biden added.

Leading the charge on voting rights is the second high-profile assignment for the vice president Kamala Harris in less than three months. In March, Biden entrusted Harris with leading US efforts with Mexico and therefore the Northern Triangle countries of Honduras, El Salvador, and Guatemala aimed toward improving conditions and lowering migration from the region using diplomacy.

In a statement, Harris said, “In the last election, more people voted than ever before. Since then, more than 380 bills have been introduced across the country that would make it harder for Americans to vote.” We must protect the fundamental right to vote for all Americans regardless of where they live.”

Both Biden and Harris have also asked Congress to pass HR 1 a flagship election reform bill that might update voting procedures, and therefore the John Lewis Voting Rights Advancement Act, which would prevent discriminatory changes to voting laws.
