Sen. Chuck Grassley (R-IA) said his most recent legislation is meant to keep judges in their branch of government instead of veering into “policymaking.”

Nearly two weeks have passed since Judge James Boasberg of the U.S. District Court for the District of Columbia issued a ruling prohibiting deportation flights while he oversees a case involving five immigrants with active deportation orders. The Trump administration went through with deportations, as planes were already airborne when Boasberg’s ruling came out, but flights have been paused ever since. Now, Grassley, 91, is about to introduce legislation to stop an injunction like this in the future.
