On #ConstitutionDay#, we honor our Founders’ vision and the promise of our Constitution: a government of, by and for the people. Each generation has a sacred responsibility to protect our democracy and uphold the values Americans have fought to protect.

On this date in 1787, 39 delegates signed the Constitution of the United States. #ConstitutionDay# Today, we can explore this history at the Memorial to the 56 Signers of the Declaration of Independence. Just across the Mall, the National Archives is home to the original Constitution and Declaration of Independence. NPS photos

Happy Constitution Day to all, and especially to our newest citizens! 75 new citizens of the United States officially became naturalized today at the Virginia Museum of History and Culture. It is an honor to have you as citizens of our great nation. #America250# #ConstitutionDay#

On Constitution Day, we honor the sacred document that created our Republic and has guided it for more than two centuries. Our Founders created a government of limited and separated powers, with checks and balances to ensure no one person or branch could become too powerful. And they made clear where that power ultimately comes from: We the People. May we never take that inheritance for granted. God bless America.

Happy Constitution Day! Celebrate the day by reading the Constitution. After all, it’s shorter than most bills Washington passes. And unlike most bills passed around here, somebody actually read it before it became law.

On Constitution Day, we celebrate our Democracy and recommit to a future worthy of our Founders. We must each fulfill our civic obligation enshrined in the Constitution to defend our Democracy — and that begins with our vote. -NP

Happy Constitution Day! The US Constitution is designed to realize and secure the ideals articulated in the Declaration of Independence through a system premised on the need to separate, check and balance power. The framers understood that “if men were angels no government would be necessary” and “if angels were to govern men neither internal nor external controls on government would be necessary.” The constitutional architecture has witnessed many perversions throughout recent history, including extraconstitutional assertions of authority by courts, the impotence of Congress, and the endurance of a permanent and too often unaccountable bureaucracy. But it still remains the best framework for self-government ever devised. As we celebrate 250 years of the American experiment (with 239 of those under the Constitution), we should work to usher in a constitutional renaissance that will restore that great document to its rightful place at the center of American civic life.

Happy Constitution Day - a day that deserves a heck of a lot of celebration AND serious analysis of how to ensure our constitutional order remains resilient among many threats. To the 14% of Americans who "don't really care about the Constitution," please come to my office hours
