The federal government yesterday began refunding more than $166B from global tariffs struck down by the Supreme Court in February, with interest accruing at roughly $22M per day.
Only companies that paid tariffs directly are eligible for refunds, not consumers indirectly hit by higher prices. Amid class-action lawsuits, companies including FedEx and Costco have said they may share proceeds with customers, though details are unclear. The refund timeline is also uncertain: The government estimates it will take 60 to 90 days to issue refunds, but technical challenges could cause delays. A digital claims system had to be built to identify the global tariffs, process refunds, and issue payments. That platform can currently handle about 63% of affected import filings, with the remainder to follow.
After the Supreme Court's ruling, the Trump administration implemented a temporary 10% tariff on most imports and is exploring a new pathway for global tariffs under the Trade Act of 1974 (101 here). |
Boston's Defending Champions |
Kenya’s John Korir won yesterday’s Boston Marathon for the second year in a row, finishing the men’s race in 2 hours, 1 minute, 52 seconds—a course record. Kenya’s Sharon Lokedi won the women’s side, also for the second consecutive year, in 2:18:51. See photos here.
This year, runners passed a 5-foot-6-inch bronze statue of Bobbi Gibb, the first woman to complete the Boston Marathon in 1966. Gibb had defied rules against women’s participation and hid in the bushes near the starting line, finishing her race in 3:21:40 and unofficially running the next two races (women were allowed to race the marathon beginning in 1972). Now 83, Gibb made the sculpture herself; see here.
The Boston Marathon is the world's oldest annual marathon, inspired by the first modern Olympic marathon in 1896. It is held every year on Patriots' Day, the state holiday commemorating Paul Revere’s 1775 midnight ride and the inaugural battles of the American Revolution. |
UK Vetting Failure Fallout |
UK Prime Minister Keir Starmer told Parliament yesterday he was wrong to appoint Peter Mandelson—whose ties to Jeffrey Epstein later emerged—as ambassador to the US, saying Foreign Office officials overrode a security clearance denial without informing him. Starmer faces calls to resign for misleading Parliament.
Mandelson, a veteran politician, was fired from his ambassadorship in September 2025 after US Justice Department documents revealed he allegedly passed sensitive government information to Epstein in 2009. British police arrested Mandelson in February on suspicion of misconduct in public office; he was released without charge and denies any wrongdoing.
The scandal has exposed gaps in the UK's appointment process: Vetting didn't begin until after Mandelson's role was publicly announced. Starmer said the process has been revised so full clearance is completed before appointments are made. A fired Foreign Office official, whom Starmer blamed, is set to give his own account today. See how the vetting process works here. |
