The word “McCarthyism” is overused, but in this case it’s mild. Liz Cheney, the former vice president’s ambitious daughter, has in her hand a list of Justice Department lawyers whose “values” she has the gall to question. She ought to spend the time examining her own principles, if she can find them. A group that Liz Cheney co-chairs, called Keep America Safe, has spent the past two weeks scurrilously attacking the Justice Department officials because they “represented or advocated for terrorist detainees” before joining the administration. In other words, they did what lawyers are supposed to do in this country: ensure that even the most unpopular defendants have adequate legal representation and that the government obeys the law.
