Lawmakers in Oklahoma have sent the state’s governor a bill that has been described as one of the most sweeping anti-immigrant laws in the country. The bill would make it a felony in Oklahoma for anyone to harbor or transport people they know to be undocumented immigrants. Violators of the law could be punished by up to a year in jail. Critics of the bill say it could result in the jailing of medical staff and religious workers who offer aid to undocumented immigrants.
