That would be the statement about slavery.
In
the first draft of the Declaration of Independence, Thomas Jefferson
wrote a lengthy part about the evils of slavery. In the paragraph that
was later left out Jefferson is actually blaming the king for the issue
of slavery. We see here that it is seen that slavery is the sin
committed by Britain. The exclusion of this paragraph tells us that
slavery was an issue even when the United States were deciding to fight
for their independence.
