WASHINGTON — The craic wasn’t all good at the White House Wednesday, as President Trump hosted Irish Prime Minister Micheál Martin in the Oval Office — and used the pre-St. Patrick’s Day meeting to attack the European Union over trade and defend his market-rattling tariff policies.

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.
