Justices’ 5-4 ruling permits Trump administration appeal to block lower court order halting above-ground work

A divided US supreme court has permitted Donald Trump to continue building his controversial $400m White House ballroom despite legal challenges, raising the likelihood it will be completed.

In a 5-4 ruling, the justices permitted the Trump administration’s request to ⁠block a lower court order that had halted above-ground construction of the project while a lawsuit by a historic preservation group seeks to block it.
