The president's latest threat puts celebrity-linked jets and thousands of U.S. aerospace suppliers in the spotlight.

Trump's swipe at Bombardier has spurred rebuttals from some Republican in states where Bombardier maintains a presence.

Bombardier is defending its deep U.S. footprint after President Donald Trump threatened to block the Canadian aircraft maker from selling its jets in the United States unless it manufactures them on American soil, prompting Republican lawmakers from Kansas to push back over the potential impact on U.S. jobs and aerospace operations.

Bombardier’s Wichita workforce primarily focuses on defense work, including preparing Canadian-manufactured planes for the U.S. Air Force.
