Trusten Polk takes the oath of office to become Missouri’s new governor. A Delaware native and Yale University graduate who became a lawyer, Polk served for just days before resigning on Feb. 27 because the legislature had appointed him to represent Missouri in the US Senate. He served there until early 1862, when he was expelled for supporting the Confederacy, according to a history from the National Governors Association.
