The US Justice Department is fast-tracking fights over President Donald Trump’s efforts to push the bounds of executive power, teeing up key issues for the US Supreme Court in the coming weeks or even days.

The Trump administration asked the Supreme Court to halt the district court ruling blocking mass firings until a federal appeals court rules on whether to uphold it or not. Justices could also decide to take up the case for oral arguments and issue a ruling themselves on whether or not to allow the firings.
