By Andrea Shalal, David Lawder and Jarrett Renshaw WASHINGTON (Reuters) -Donald Trump threatened on Wednesday to escalate a global trade war with further tariffs on European Union goods, as major U.S.

European Commission President Ursula von der Leyen said as the United States is “applying tariffs worth 28 billion dollars, we are responding with countermeasures worth 26 billion euros,” or about $28 billion.

Escalating a trade war with Europe, President Donald Trump said his administration will counter the European Union's new tariffs on the US.
