"American Idol" star David Archuleta was in town Friday for a special tour befitting the holiday weekend: The National Archives

Aruchuleta tweeted Friday afternoon:

"At the National Archives. Way cool! All these incredible documents. Declaration of Independence, The Constitution, neat stuff."

At only 16 years old, Archuleta was the runner-up in the 2008 season of the wildly popular talent show, and has since released a number of albums and singles. His next single is due for release on July 13, but producers have yet to announce the title.
