Note:A previous version of this article mistakenly identified Elizabeth Coulson's political affiliation. Coulson is a Republican. The article also incorrectly identified Coulson's relationship with Robert Coulson, and her alma mater. Mr. Coulson is her father-in-law, and Coulson attended Wellesley College.
