Beginning with the Declaration of Independence in 1776, Jefferson introduced strong wording in the initial draft condemning the practices and processes of the slave trade.
In the Virginia Assembly, in the 1788, legislator Jefferson supported a bill to prohibit the state from importing slaves.
Next, in the 1784 Congress, Jefferson proposed federal legislation banning slavery in the New Territories of the Northwest.
As President in 1807 he signed a bill prohibiting the US from participating in the international slave trade.
Perhaps you somehow missed what I said to you in my previous post, so allow me to repeat it: Jefferson had slaves on his plantation throughout his life, and lived well off their labor. Further, he did not free them at his death as did Washington (except for two of Sally Hemming's family); nor did he educate them--as did Washington. And here are a few more of his deeds (from Wiki, well-referenced):
In 1798 his friend Tadeusz Kościuszko, a hero of the Revolution, entrusted Jefferson with his American estate and will, by which he intended slaves to be purchased for freedom, as he strongly supported abolitionism. He died in 1817, but Jefferson never executed his will, although he could have freed all his own slaves with the money, at no cost to himself.[8]
And then there's this:
As governor of Virginia for two years during the Revolution, Jefferson signed a bill to promote military enlistment by giving white men land, "a healthy sound Negro...or £60 in gold or silver."[37]
While president, he refused to recognize the new nation of Haiti--because there had been a slave revolt there. Liberty for me but not for thee.
What a phony your hero was.
