Sen. Tammy Duckworth (D-Ill.) urges the Federal Aviation Administration (FAA) to reject any White House pressure to approve President Donald Trump’s planned triumphal arch near the Lincoln Memorial. Multiple outlets report that in a letter sent Thursday, Duckworth questions whether the FAA is being asked to prioritize the “Independence Arch” (described in some reports as about 79 meters, or roughly 250 feet) over aviation safety and public interests.

Duckworth, the top Senate Democrat on the Senate Commerce Subcommittee on Aviation, characterizes the proposal as a political or personal project and raises concerns that the structure could pose risks to commercial flights and run counter to efforts to improve safety in Washington, D.C.’s airspace. Several reports state she also asks whether the White House has pressured the FAA to fast-track or otherwise give preferential treatment to the arch’s approval.

The outlets agree the core issue is whether aviation-safety considerations are being subordinated to the administration’s project timeline or preferences. The reports do not describe the FAA’s response in the provided excerpts.
