FIVE MINUTE DAILY

The national debt officially hit $40 trillion on Wednesday, a milestone reached faster than any previous trillion-dollar threshold in American history. Trump campaigned on fiscal discipline. The number kept climbing anyway.

Spending on the Iran war, extended tax cuts, and tariff refunds to affected industries have all outpaced any offsetting revenue. Interest payments alone now rival the defense budget, leaving Congress with fewer levers to pull the next time markets get nervous.

Trump paused 50% tariffs on $20 billion of Canadian imports less than two hours before they took effect, pushing the deadline to Saturday. Speaking during a South Lawn construction tour, he called it a very fair deal for both sides, subject to the finalization of documents.

US Trade Representative Jamieson Greer said Washington is "very happy" after a 45-minute meeting, and that the agreement removes longstanding irritants with Ottawa. Canada's trade minister Dominic LeBlanc flew home to brief Mark Carney, who spent the day chairing Cabinet and a call with provincial leaders.

A personalized mRNA vaccine from Merck and Moderna stopped melanoma returning in high-risk patients after surgery, when given alongside the immunotherapy drug Keytruda. Called Intismeran, the shot significantly extended the period patients stayed cancer free compared with Keytruda administered on its own.

Researchers are calling the result a breakthrough while urging caution, because the full trial data has not yet been released or peer reviewed. Even after the trial concludes, the treatment faces regulatory approval and a further NHS approval process before any British patient receives it.

Lebanon extradited Maj. Gen. Adel Issa to Damascus, the first military officer it has surrendered since Bashar Assad's government collapsed in late 2024. Syria's interior ministry says Issa faces charges of intentional killing, torture resulting in death, and inciting sectarian strife.

The United Arab Emirates announced a full halt to trade with Iran, severing what analysts have long described as Tehran's most important commercial lifeline for evading sanctions. The move aligns Abu Dhabi squarely with the Trump administration's pressure campaign, though Emirati officials deny ever having facilitated sanctions evasion.

Mykhailo Fedorov, the fired ex-defense minister and one of Ukraine's most popular young politicians, publicly called for wartime elections, arguing Russia shouldn't dictate when Ukrainians choose their government. The break marks the sharpest public rupture inside Zelensky's former inner circle since the war began.

Trump tapped Heidi Overton, a physician and deputy director of the White House Domestic Policy Council, to run the Food and Drug Administration. She inherits a to-do list ranging from GLP-1 supply headaches to accelerated approval reforms and a restive biotech industry.

Dr. David Morens, a former aide to Dr. Anthony Fauci, pleaded guilty to violating federal law by concealing emails related to COVID-19 origins research. The case has become a flashpoint for congressional Republicans investigating pandemic-era transparency at NIH.

Congress has rewritten the terms of existing income-based repayment plans, forcing many borrowers onto plans with higher monthly payments and longer forgiveness timelines. Retroactive changes to signed loan contracts are unusual, and borrower advocates are already exploring legal challenges.

Secretary Scott Bessent's Treasury doubled the size of its debt buyback operations, targeting the longer end of the curve to calm a bond market that had been drifting higher on debt-ceiling anxiety. Yields moved lower on the announcement.

Target beat Q2 estimates and raised full-year guidance, citing a large tariff refund and early signs its long-promised turnaround is finally taking hold. Comparable sales grew for the first time in several quarters, with traffic notably positive.

The milestone comes as China accelerates commercial spaceflight investment across a dozen private launch firms.

NASA has abandoned efforts to save the Swift Observatory, the 21-year-old gamma-ray burst hunter now expected to burn up on atmospheric reentry. Swift's loss leaves astronomers with a smaller toolkit for chasing the most violent explosions in the universe.

Japanese researchers studying supercentenarians identified an unusual immune cell that appears around age 100 and may help the body fend off the chronic ailments of aging. If replicable, the finding could reshape how researchers think about extending healthy lifespan, not just lifespan.

Two-time champion and longtime players' union president Nneka Ogwumike announced her retirement at 36, closing out a 15-season career that ranks her among the league's all-time leaders in scoring and rebounding. She leaves the game just as the WNBA enters its most lucrative broadcast era ever.

Dallas Wings rookie and No. 1 overall pick Azzi Fudd will undergo right knee surgery and miss the rest of the WNBA season after weeks of lingering soreness. The former UConn star hasn't played since August 5, cutting short one of the most-watched rookie campaigns in years.

Charlie Hunnam is reassembling the Sons of Anarchy cast for a new FX meta-thriller called Legends, which he co-created with Jonathan Groff and will also star in. The limited series arrives more than a decade after the original biker drama ended.

Sandra Bullock broke a years-long silence on partner Bryan Randall's ALS diagnosis during a candid appearance on the SmartLess podcast with Jason Bateman. She described the period as "pretty dark," saying she "wasn't allowed to speak about it" while it was happening.

Beninese icon Angélique Kidjo became the first African musician honored with a star on the Hollywood Walk of Fame. The 66-year-old five-time Grammy winner used her speech to remind the crowd that "without Africans, no music is possible on this planet."

What it is: A quietly booming corner of finance where hedge funds, private equity firms, and specialty lenders bankroll personal injury lawsuits in exchange for a slice of any eventual payout. What used to be niche is now a multi-billion-dollar industry with its own ratings, secondary markets, and investor pitch decks.

The detail: Litigation funders advance cash to plaintiffs and their law firms — covering expert witnesses, medical bills, and living expenses — while cases drag on for years. If the plaintiff wins or settles, funders collect their principal plus a return that can easily exceed venture-capital-level yields. If the case loses, they eat the loss. That's why the biggest firms now run massive portfolios to smooth out results.

Why it matters: The money has changed how injury cases work. Verdicts have exploded in size, so-called "nuclear" awards above $10 million are increasingly common, and cases that would have settled quickly for six figures now stretch on for years while funders wait for a bigger payday. Defendants — insurers, hospitals, trucking companies — argue the model inflates payouts and ultimately raises costs for everyone. Plaintiffs' lawyers counter that funding lets ordinary people go the distance against corporate defendants who used to outlast them.

What to watch: A handful of states are moving to require disclosure of who's funding a lawsuit, and Congress has floated similar rules at the federal level. Meanwhile, the industry is pushing further upstream, funding mass tort dockets and even bundling cases into securitized products. Whether regulators treat litigation finance more like insurance, lending, or securities will shape whether the next $40 trillion of American debt has a courtroom cousin.
