Like with his White House ballroom project, Trump has stirred controversy by not seeking congressional input for such a major project.

President Donald Trump's plan to build a triumphal arch in Washington is getting another look from a federal agency that suggested changes before it approved the concept last month

At a height of 250 feet, the arch would dwarf the Lincoln Memorial and be close to half the height of the Washington Monument, an obelisk that is about 555 feet tall.
