Gunn was born in Virginia to John and Mary Gunn and became a lawyer. Gunn served in the 1st Continental Dragoons during the Revolutionary War. He moved to Georgia after the war and became a significant political figure in his new home, establishing himself in short order as a planter, magistrate, state legislator, and militia officer, where he rose to brigadier general in the 1st Brigade of the Georgia militia in 1792.
Between 1782 and 1789, Gunn unsuccessfully challenged retired Gen. Nathanael Greene to a duel, assailed Georgia Revolutionary War hero James Jackson in the press, and defeated Gen. Anthony Wayne for one of Georgia's First U.S. Senate seats in January 1789. Gunn was selected as a delegate to the Continental Congress in 1787 but never attended sessions.
In his first term as senator, between mid-May and late June 1789, Gunn moved from opposing the establishment of excise taxes to supporting them. He also opposed giving the president the power to remove heads of cabinet departments without the advice and consent of the Senate. The administration negotiated the Treaty of New York (1790) with the Creek Indians, which greatly angered many in Georgia. Gunn voted against the treaty. Like no other senator, Gunn impacted the internal processes in the Senate and the relationship between the executive and legislative branches of the newly formed government during his first term in office.
Gunn's rivalry with James Jackson, which had originated in Georgia in the period between the end of the Revolution and the launching of the new federal government, heated up in the early 1790s. Gunn was a Federalist, and Jackson was a Jeffersonian. Gunn supported the formation of the Georgia Company and the sale of the Yazoo lands. In the aftermath of the Yazoo sale, Gunn acted quickly to complete the transaction and protect it in Washington, while Jackson tried to block completion of the sale. On June 24, 1795, Gunn voted in favor of the Jay Treaty, one of only two southern senators to do so. James Jackson voted against it. Jackson resigned from the Senate and returned to Georgia to work against Gunn, who fell in public opinion due to the Yazoo land fraud.
Gunn was re-elected in 1795 and served out his second term until March 1801.
