1. Trump talks trade: President Donald Trump is set to meet with European Commission President Jean-Claude Juncker on Wednesday.

The two leaders "will focus on improving transatlantic trade and forging a stronger economic partnership," the White House said.

The United States has already put tariffs on aluminum and steel imports from the European Union, and now Trump is threatening to hike tariffs on cars made in Europe to 20%. EU officials hope the trip will help defuse the tension.

The United States and European Union have the world's largest bilateral trading relationship, worth over $1.1 trillion a year.
