US President Donald Trump has increased tariffs to 15%, one day after a US Supreme Court decision struck down his sweeping import taxes
In a post on Truth Social, Trump writes that over "the next short number of months, the Trump Administration will determine and issue the new and legally permissible Tariffs"
A former trade negotiator tells the BBC it isn't a surprise that Trump set global trade levies to the maximum legal rate - but says he expected the president to do it earlier
Yesterday, the president called the Supreme Court's decision "deeply disappointing" - today, he derided the nation's top court further, calling the ruling "ridiculous, poorly written, and extraordinarily anti-American"
With a 6-3 majority, the court ruled Trump exceeded his authority when he imposed tariffs via a law reserved for national emergencies - they say he needs congressional approval to impose taxes on imports
The Supreme Court's ruling has diminished Trump's tariff threat-as-diplomacy tool - but it hasn't entirely gone away with this decision, writes the BBC's Washington correspondent
