People across the United States are marching on Saturday to demand that Congress pass sweeping voting rights legislation and that state lawmakers halt efforts to enact bills that restrict voting access.

The “March On for Voting Rights” will host its flagship event in Washington DC, but marches will also take place in other major cities, including Atlanta, Miami, Phoenix and Houston.

Marchers in Washington will gather at the Lincoln Memorial to commemorate the 58th anniversary of the historic 1963 civil rights march on Washington, where Martin Luther King Jr. delivered his famous “I Have a Dream” speech.

Millions of people are expected to attend marches throughout the country, according to a press release from March On for Voting Rights organizers.

This will be the second consecutive year that organizers have commemorated the March on Washington with a renewed effort to fight for equality. The “Get Your Knee Off Our Necks Commitment March” in 2020 in Washington pushed for federal voting rights legislation and police reform, and came at the height of a racial reckoning sparked by George Floyd’s death.

Plans for the march were announced in June, one day after Senate Republicans blocked the For the People Act – a signature voting and election bill that Democrats had pitched to counter state-level efforts to restrict voting access. Republicans denounced the bill as a partisan power grab and a federal overreach into state voting and election systems.

What is the march route for the March on Washington?

People will gather at 8 a.m. at McPherson Square Park at 15th St., NW, and H Street, to march from McPherson Square past Black Lives Matter Plaza, passing the White House and Washington Monument.

The closing rally will take place with the backdrop of the National Mall, entering at 12th St. and Madison Drive, gathering from 7th St. to 14th St. between Jefferson Dr. and Madison Drive.

What is the purpose of this march?

Martin Luther King III, the eldest son of Martin Luther King Jr., and his wife, Arndrea Waters King, along with Rev. Al Sharpton, Andi Pringle and other voting rights leaders organized the march in an effort to urge lawmakers to pass the John Lewis Voting Rights Advancement Act.

The bill, which increases the power of the federal government and racial minorities to block or challenge election rules they find discriminatory, was passed by the House on Tuesday.

The bill faces a steep climb in the Senate, where the vast majority of Republicans oppose it, calling the legislation a massive federal overreach into the states’ role in elections. At this point, Alaska Sen. Lisa Murkowski is the only Senate Republican expected to support the bill.

“If you want to understand why the vote is so important, look at the last 4 years, the last 10 years, and the last 100 years,” Rev. Al Sharpton, who heads the National Action Network, said in a statement “Freedom fighter and Congressman John Lewis knew it was essential that every vote must count in order to assure every voice is represented, but unfortunately through federal voter suppression and gerrymandering, that hasn’t been the case.”

“Whether in Congress, in the streets, or during our March On for Voting Rights, this is the summer of activism,” he added.

Who sponsored and funded the march?

The march is sponsored by Drum Major Institute, March On, the National Action Network, Future Coalition, SEIU, and 51 for 51, and is funded by the #ForJohn campaign.

The campaign was launched by Martin Luther King III, and his wife, Arndrea King, to raise money for local organizers in critical states who are fighting for equal voting rights and pressing their Senators to pass election reform legislation.

Who will be on stage?

Elected officials, civil rights leaders, youth organizers, community activists and others will join Rev. Sharpton, Martin Luther King III and Arndrea Waters King on the stage.

Many speakers, including Martin Luther King Jr.’s granddaughter and activist Yolanda Renee King; Philonise Floyd, activist and brother of George Floyd; NAACP President Derrick Johnson; and Washington DC Mayor Muriel Bowser will address the marchers.

“Coretta Scott King told us, ‘Freedom is never really won, you earn it and win it in every generation,’” Arndrea Waters King, Drum Major Institute president, said in a statement. “Now is the time to earn and win our sacred right to vote. It is up to us to remind Congress they represent the people, and the people demand the passage of the John Lewis Voting Rights Restoration Act.”
