Last July, Trump and Ursula von der Leyen struck a trade deal in Scotland.

It was built to protect a relationship worth almost 1.68 trillion euros.
But now, the European Parliament is pushing back.
After a US Supreme Court ruling against the tariffs, Washington introduced new duties on steel and aluminium, effectively violating the treaty before signature.
