Early in his first term George Washington made tour of the New England states. At that time Rhode Island had not ratified the constitution so he skipped that state, In the summer of 1790 Rhode Island ratified the constitution and Washington, with Jefferson and New York governor Clinton in tow, set out for a visit.
At their first stop, Newport, the party was greeted by Moses Seixas. He was a merchant and spokesman for his congregation, Yeshuat Israel. In part of his greeting he noted that his congregation had been deprived of the"invaluable rights of free citizens."
Washington wrote this letter in reply. The underlined sections make it plain that he saw America as a place where we would all be free to worship as we believed and that one group was not set above another.
