What the Evidence Shows
All ten independent and reputable news sources consistently report that President Donald Trump announced an increase in the global tariff rate on imports to the United States from an initial 10% to 15%. This announcement came shortly after the U.S. Supreme Court struck down a previous set of sweeping tariffs, prompting the administration to adjust its tariff policy.
The sources indicate that the 15% rate is the maximum allowed under existing legislation for a temporary period (up to 150 days), during which the administration plans to develop new legally permissible tariffs. There is no contradictory evidence in the sources provided, and all confirm the timing as February 21, 2026, making this a current and verified statement by President Trump.
