Trump's triumphal arch proposal

The proposed structure would tower over other famous arches around the world, including the Arc de Triomphe in Paris.

Trump has touted the design as a necessary addition to the capital's skyline, though the project has already faced criticism over its cost and aesthetic impact.

Architectural experts have also warned against the president's desire to use a 'magic paint' on nearby federal buildings to match the monument's appearance.

The proposal is expected to trigger a heated debate in Congress over the use of public land and federal funds for such a large-scale commemorative project.
