Admitted to the Virginia bar in 1838, Bedinger began a private legal practice in Shepherdstown. His law partner and soon brother in law was George Rust. Bedinger lived in Shepherdstown during the enumerations of both the 1840 and 1850 federal censuses. In the more detailed 1850 census, his household also included New York born Caroline Bedinger, age 22, and Mary McKenna, a 27 year old Virginia born free woman (presumably a servant), and a nine year old enslaved girl. A decade earlier, Bedinger and his first wife lived with two enslaved blacks (a man and woman both between 10 and 24 years old), and his 60+ year old mother lived nearby with a free white female in her twenties and nine slaves. In 1844, Bedinger running as a
Democrat, defeated his legal mentor, and won a seat in the
United States House of Representatives. He also defeated a
Whig opponent in 1847, serving from 1845 to 1849. While in Congress, Bedinger denounced Whig efforts to restrict voting by Irish and German immigrants, such as his family and many neighbors. Furthermore, he endorsed the Walker Tariff of 1846 that reduced duties on some imported goods, as well as applauded Texas's annexation and admission as a slave state. Although Bedinger supported President James K. Polk's expansionist policy in the Pacific Northwest, he advised against confronting Great Britain concerning the
Oregon Territory. After losing his next reelection campaign, Bedinger resumed practicing law, at first in New York, then back in Virginia. Fellow Democrat, President
Franklin Pierce, appointed him Chargé d'Affaires to Denmark in May 1853. The following year he received a promotion (and salary increase) to minister plenipotiary, as he had become a favorite at the court of King Frederick VII and was engaged in negotiation for the abolition of the Danish Sound Dues, a toll exacted on all ships navigating between the North Sea and Baltic Sea. The annual assessment for U.S. ships was about $100,000 and Bedinger announced that the U.S. would abrogate its 1826 commercial treaty with Denmark. This prompted Denmark to call a general European conference at which Denmark agreed to abolish the duty in exchange for other participants agreeing to compensate the country for maintaining the channel and lighthouses. Although the United States did not participate in the European conference, Bedinger arranged a bilateral agreement which gave American ships free passage in exchange for a small contribution to the general fund which the European treaty created. Thus Bedinger became the first
United States Ambassador to Denmark, effectively from 1853 to 1858. Despite his diplomatic triumph, Bedinger found his salary did not even cover his expenses in Denmark and so resigned, agreeing to remain in Denmark until his successor's appointment and confirmation, which occurred in 1858. Not long after his resignation as a diplomat, Bedinger was named superintendent of the United States armory at
Harpers Ferry, not far from his Shepherdstown home. ==Death and legacy==
