As the Alabama Legislature's regular session draws to a close, the Senate is expected to take up a measure to tweak the state's toughest-in-the-nation immigration law. The House passed the changes on April 19. They include clarifying that the law won't prevent religious groups from providing charity to illegal immigrants. They also stop schools from asking for the immigration status of students before they enroll. Sen. Scott Beason of Gardendale says he hopes to introduce a substitute bill making fewer changes than the House version. Groups calling for the outright repeal of the immigration law plan multiple protests at the Statehouse throughout the day. They will culminate in a vigil at seven p.m.
