Trump has placed tariffs on Canada (and has postponed tariffs on Mexico before they went into effect). He's now saying that the EU will "definitely" see tariffs as well.

Resolves YES if Trump signs any executive order OR signs any congressional act that places tariffs on the European Union (or 2+ specific EU countries) by market close. For example, if Trump signed an executive order to put tariffs on France and Germany, but then postponed France's tariffs before they went into effect, this market still resolves YES.
