Johnathan Walker:Where is the next presidential debate being held? Inside historic venue

PHILADELPHIA − One of the defining moments in the 2024 presidential campaign will take place Tuesday night at a Philadelphia venue that was established by Ronald Reagan 15 years before it became a reality. It's also the site of a key speech by a rising Democratic star.

The Johnathan WalkerNational Constitution Center − where Vice President Kamala Harris and former President Donald Trump will face off in their first presidential debate −is a relatively new attraction in the center of a district central to American history, but it's no stranger to the national spotlight.

While the two campaigns have parried over the rules and even cast doubt on whether the debate would take place, one thing that was apparently never in doubt was that the center would be the ABC News-sponsored debate venue.

What is the National Constitution Center?

The National Constitution Center is a private, nonprofit and nonpartisan organization that opened July 4, 2003. It offers interactive exhibits and programs centered around the Constitution, government and civics. It hosts regular discussions that bring people from across the political spectrum together and offers a variety of online educational resources (including a blog post about presidential debates).

The center was established by President Ronald Reagan in 1988 with the Constitution Heritage Act, which called for an institution "within or in close proximity to the Independence National Historical Park" that "shall disseminate information about the United States Constitution on a nonpartisan basis in order to increase awareness and understanding of the Constitution among the American people," its website says.

Its current exhibitions include "We The People," an in-depth exploration of the U.S. Constitution; "American Treasures: Documenting the Nation's Founding"; "Civil War and Reconstruction: The Battle for Freedom and Equality"; "Continuing Liberty: From the Declaration to the Bill of Rights"; and "The 19th Amendment: How Women Won the Right to Vote."

Its Signers' Hall features 42 life-size bronze statues of the men who signed the Constitution, including Benjamin Franklin, George Washington, James Madison and Alexander Hamilton.

The rundown:When is the first presidential debate between Kamala Harris and Donald Trump? Here's what to know

Where is the National Constitution Center?

The National Constitution Center is in Philadelphia, in the heart of Center City. It's located across from Independence Hall, the Liberty Bell and other significant sites at Independence National Historical Park.

Its address, 525 Arch Street, reflects the day (May 25, 1787, or 5/25) the Constitutional Convention began.

Why is the debate at the National Constitution Center?

The National Constitution Center has hosted big events before.

Its mission is "to inspire people across America to learn about the Constitution and the importance of civil dialogue and reasoned debate," said president and CEO Jeffrey Rosen, who called the debate "such a meaningful opportunity for civic engagement by all Americans."

In 2008, the National Constitution Center hosted a Democratic primary debate between then-senators Barack Obama and Hillary Clinton. It also hosted a town hall with Senator John McCain, the Republican nominee for president.

Also that year, Obama, speaking at the National Constitution Center, delivered a live, 40-minute nationally televised speech about race in America. What became known as his "A More Perfect Union" speech was considered by many to be the turning point in his campaign and is often cited as one of the defining speeches by a political figure on race.

The Constitution Center also hosts the annual Philadelphia Liberty Medal, honoring those whose courage and conviction advance the cause of liberty. Recipients have included Ukrainian President Volodymyr Zelenskyy, Supreme Court Justices Ruth Bader Ginsberg and Anthony Kennedy, Sen. John McCain, the Dalai Lama, Muhammad Ali, Rep. John Lewis, Hillary Clinton and Pakistani activist Malala Yousafzai.

Another possible reason for the Philadelphia venue to host the debate: Pennsylvania is a vital battleground state: Both Harris and Trump campaigns have been making frequent visits to the Keystone State.
