(二)The U.S. Justice Department has dispatched an experienced federal hate crimes lawyerto Iowa to help prosecute a man charged with murdering a transgender high schoolstudent last year, a highly unusual move that officials said was personally initiated byAttorney General Jeff Sessions. In taking the step, Sessions, a staunch conservative, is sending a signal that he hasmade a priority of fighting violence against transgender people individually, even as hehas rolled back legal protections for them collectively. The Justice Department rarely assigns its lawyers to serve as local prosecutors, andonly in cases in which they can provide expertise in areas that the federal governmentviews as significant. By doing so in this instance, Sessions put the weight of thegovernment behind a small-city murder case with overtones of gender identity andsexuality.（20 分）
