The U.S. Supreme Court swept away this week another obstacle to one of President Donald Trump's most aggressively pursued policies - mass deportation - again showing its willingness to back his hardline approach to immigration.

The administration had asked the court to allow it to end deportation protections for more than 500,000 people facing dire humanitarian crises in their home countries.

During a rally at a steel plant the US president announced that he will double tariffs on steel imports. Afterwards, he announced the same for aluminium. The measure, which would hit Europe hard, is supposed to come into force on 4 June.

President Donald announced a 50% tariff on steel made outside the United States as he touted a partnership between Japan's Nippon Steel Corporation and the United States Steel Corporation during a rally near Pittsburgh.

This week’s ruling blocking many of the president’s tariffs will not lift those on Canadian cars, steel and aluminum. A trade expert explains what’s next.

The May 29 ruling by the United States Court of Appeals for the Federal Circuit means Trump will still be able to wield his chief economic tool in the short term.
