Begining at the 13 minute segment, President Obama answers Chuck Todd's question about the 14th Amendment by discussing the "debt ceiling", creditors being liable to their debtors, and Congress' power to enforce, by appropriate legislation, the provisions of this article.
Below are Amendments 1 through 13 (aka Articles I through XIII) as they were printed in 1853 and 1868.
Notice the wording of Article XIII (the 13th Amendment) as it was memorialized in the 1853 edition of The American's Own Book:
From the 1868 edition of The Voter's Text Book notice the change in the 13th Amendment (Article XIII). Be sure to read the foot note on page 40.
Did you read the foot note on page 40 of the 1868 edition of The Voter's Text Book?
When was the 13th Amendment ratified?
Does the 13th Amendment allow for 'voluntary servitude'?
Who has the Power to legislate "slavery" and enforce 'voluntary servitude' by coercion? (See Section 2 of the 13th Amendment.)
How is it that Article XIII was "approved February 1, 1863" and not shown as "ratified by the constitutional number of States" by 1868 when The Voter's Text Book was published?
