James Wilson Grimes (October 20, 1816 – February 7, 1872) was an American politician, serving as the third Governor of Iowa and a United States Senator from Iowa. Biography Born in Deering, New Hampshire, Grimes graduated from Hampton Academy and attended Dartmouth College. He studied law, moved west and commenced practice in a settlement in 'Black Hawk Purchase', Wisconsin Territory, that was later incorporated as Burlington, Iowa. He also farmed. Grimes served as a member of the Iowa Territorial House of Representatives for the 1838–1839 and 1843–1844 terms. He served as Governor of Iowa from 1854 to 1858. While elected as a Whig in 1854, he was a guiding light in the Republican Party's establishment in Iowa in 1855 and 1856. U.S. Senate Grimes was elected as a Republican to the U.S. Senate in 1859 and reelected in 1865. He served in the Senate from March 4, 1859, until December 6, 1869, when he resigned due to ill health. In the Senate, he served as chairman of the Committee on the District of Columbia (in the 37th and 38th Congresses), and the Committee on Naval Affairs (in the 39th through 41st Congresses).

They were joined in bucking their party by three other Republican senators, James Dixon, James Rood Doolittle, Daniel Sheldon Norton After the trial, Congressman Benjamin Butler conducted hearings on the widespread reports that Republican senators had been bribed to vote for Johnson's acquittal. In Butler's hearings, and in subsequent inquiries, there was increasing evidence that some acquittal votes
