The Supreme Court opened its new term Monday, hearing oral arguments in a case that will determine who’s eligible for reduced prison sentences under the the First Step Act, which rolls back mandatory minimum sentences for certain people convicted of nonviolent drug charges. Today Supreme Court justices are hearing a case brought by a predatory payday lending group challenging the leadership structure of the Consumer Financial Protection Bureau. Legal experts warn the outcome of the case could undermine other regulatory agencies and federal programs, including Medicare and Social Security.
