The National Trust for Historic Preservation filed a lawsuit against the President Donald Trump administration to block construction of a ballroom.

The National Trust for Historic Preservation argues Trump exceeded his constitutional authority by not seeking congressional approval for a project of this scale.

A nonprofit organisation tasked by the US Congress with helping preserve historic sites has sued the White House to stop construction on President Donald Trump's new ballroom.

The lawsuit argues that President Trump was legally required to get federal approvals before demolishing the historic East Wing of the White House.

Trump has championed 90,000-square-foot addition, as critics say his has circumvented legally required approvals.
