The justices intervened Monday after lower courts found work must stop because the project doesn't have congressional approval.

The Supreme Court temporarily cleared the way for construction of President Trump's White House ballroom to continue while the justices consider his administration's appeal. White House correspondent Liz Landers reports on the ballroom as well as the president's IndyCar race coming to the nation's capital this weekend.

The temporary order comes hours before lower-court rulings would have forced a halt to aboveground construction.
