Legal expert challenges war powers clock pause interpretation
Katherine Yon Ebright, counsel at the Brennan Center's Liberty and National Security Program, stated that the administration's interpretation of pausing the War Powers Resolution 60-day clock would constitute a significant extension of previous legal arguments.
