And to celebrate, Philadelphia's National Constitution Center is offering free admission today.
The Constitution Day celebration features a wide range of FREE educational festivities and timely constitutional conversations with leading scholars and experts.
For example, Rep. John Lewis of Georgia will lead students in reading the Preamble to the Constitution at 8:30 a.m. on the museum's front lawn. After that, the museum's new flagpole will be dedicated during a special flag-raising ceremony.
At 10:30 a.m., 50 new American citizens will be sworn in. And at noon, there will be cake for all guests.
