The Institute on the Constitution Again Falsely Ascribes Quote to Thomas Jefferson (UPDATED)

If the Institute on the Constitution leaders can’t get these easy quotes right, then how can they be trusted to teach the Constitution?
This time it is Jefferson again. IOTC has Jefferson saying, “That government is best which governs least.” According to the ever reliable Anna Berkes at Monticello, Jefferson didn’t make that quote. 
iotc jefferson governs least
The IOTC has falsely attributed quotes to George Washington (twice), Thomas Paine, and to Jefferson (twice). It certainly looks like they don’t care. To my knowledge, they have never corrected the false information or removed the fake quotes.
UPDATE: Someone who runs the IOTC Facebook page said the following in response to my assertion that the Jefferson quote was false.

Actually he quoted Henry David Thoreau’s work called “Civil Disobedience”. The quote is also part of his philosophy.

In fact, Jefferson died on July 4, 1826 and Civil Disobedience was published in 1849.
