Last month, the Supreme Court limited the use of nationwide injunctions, which allow judges to block policies they have found unlawful from going into effect nationwide. Now a New Hampshire judge is road-testing a substitute: He has temporarily blocked Donald Trump’s birthright citizenship executive order by certifying a class action to cover babies born in all 50 states.

But a May 22 move by the Supreme Court may signal the end of the NLRB’s independence, say labor leaders, and transform the agency into an extension of the White House. In turn, they warn, President Donald Trump could use the board to reward friends and punish enemies.

Still, the Supreme Court's expansive view of presidential power is giving Trump significant leeway -- with potentially more to come headed into the summer.
