This article was brought to my attention today and it is very interesting. I pride myself not as an expert of anything, but a life-long daily student. We as Americans, in this time of such religious extremism rhetoric owe it to ourselves to understand our own history and to appreciate just how diverse the thought process was that went into the founding of this nation.
There is so much misinformation out there. Intentional propaganda that is meant to control groups by the use of fear and paranoia. One of the main themes of this propaganda has been to nurture and inflate anti-Muslim sentiments in the United States as we have seen all too clearly as of late. With that said, I would like to share this article with you and I will post a few paragraphs to get you intrigued…

The true history of the Koran in America
By Ted WidmerSeptember 12, 2010
[...]For better or worse, there is not much anybody can do about religious extremists who offend decency, yet stay within the letter of the law. The same Constitution that confirms the right to worship freely protects the right to worship badly. But September is also the anniversary of the 1787 document that framed our government, and in this season of displaced Tea Party anger, it is worth getting right with our history. There is nothing wrong with the desire to go back to the founding principles that made this nation great — but we should take the time to discover what those principles actually were.For most Americans, the Koran remains a deeply foreign book, full of strange invocations. Few non-Muslims read it, and most of us carry assumptions about a work of scripture that we assume to be hostile, though it affirms many of the earlier traditions of Christianity and Judaism. Like all works of scripture, it is complex and sometimes contradictory, full of soothing as well as frightening passages. But for those willing to make a genuine effort, there are important areas of overlap, waiting to be found.
[...]Reports of Korans in American libraries go back at least to 1683, when an early settler of Germantown, Pa., brought a German version to these shores. Despite its foreign air, Adams’s Koran had a strong New England pedigree. The first Koran published in the United States, it was printed in Springfield in 1806.
Why would John Adams and a cluster of farmers in the Connecticut valley have bought copies of the Koran in 1806? Surprisingly, there was a long tradition of New Englanders reading in the Islamic scripture.[...]
[...]George Washington went out of his way to praise Muslims on several occasions, and suggested that he would welcome them at Mount Vernon if they were willing to work. Benjamin Franklin argued that Muslims should be able to preach to Christians if we insisted on the right to preach to them. Near the end of his life, he impersonated a Muslim essayist, to mock American hypocrisy over slavery.
Thomas Jefferson, especially, had a familiarity with Islam that borders on the astonishing. Like Adams, he owned a Koran, a 1764 English edition that he bought while studying law as a young man in Williamsburg, Va. Only two years ago, that Koran became the center of a controversy, when the first Muslim ever elected to Congress, Keith Ellison, a Democrat from Minnesota, asked if he could place his hand on it while taking his oath of office — a request that elicited tremendous screeches from the talk radio extremists. Jefferson even tried to learn Arabic, and wrote his Bill for Establishing Religious Freedom to protect “the Jew and the Gentile, the Christian and the Mahometan, the Hindoo and infidel of every denomination.”[...]
Understanding others, even those whose beliefs and viewpoints that we ourselves may not subscribe to, is key to perpetuating what the founding fathers worked so diligently to put into place…a tolerant and accepting nation made up of diverse cultures, faiths, colors and worldviews.
In 1790, as the last of the original 13 states embraced the Constitution, and the United States finally lived up to its name, George Washington visited that state — unruly Rhode Island — and its Jewish congregation at Newport. The letter he wrote to them afterwards struck the perfect note, and drained much of the antiforeign invective that was already poisoning the political atmosphere, only a year into his presidency. Addressing himself to “the children of the Stock of Abraham” (who, in theory, include Muslims as well as Jews), the president of the United States offered an expansive vision indeed:
“May the children of the Stock of Abraham, who dwell in this land, continue to merit and enjoy the good will of the other Inhabitants; while every one shall sit in safety under his own vine and figtree, and there shall be none to make him afraid.” [read full article here]

Thanks for bringing this to people's attention, Leah.
Of course they read the Koran, these were classically educated men. I am sure they studied all of the fine and liberal arts – unlike our poor children, who in some states are not even getting the true version of American history.
