On the phone, he speaks in monologues, interrupts, and leaves her hardly a moment to speak. On one call, he complained about how the British press treated him and refused to come to London unless guaranteed a warm welcome, to the disbelief of May’s aides listening in. British officials suspect he’s still displeased (he canceled a trip planned for next month), and some now regret having offered him a state visit. No matter, perhaps; they don't expect him to take it up, anyway.

Everybody’s distancing themselves from a harassment-ridden, all-male charity dinner where the Financial Times reported 130 hostesses were put on show, harassed, groped, and propositioned. Organizers, who’d had the hostesses wear skimpy outfits and parade across a stage, professed to be shocked. (Later, they said they were shutting down their charity.) Attendees rushed alternately to explain, defend themselves, or plead ignorance. And the Bank of England said a prize of tea with its governor had been re-auctioned without its approval.

How early should you get to the airport? That all depends on the lines at security, and God knows we can’t reliably predict those. Except maybe now we can. A new tool that uses a form of radar is being tested at four U.S. airports and incorporated into a mobile app. If it works, it may finally give us the ultimate piece of the puzzle, and let us spend as little time inside LaGuardia as humanly possible.

Steven Mnuchin likes his dollars weak. In Davos a day before Trump is set to arrive, his treasury secretary said the decline of the dollar, now at a three-year low amid a protectionist push, was a boon for the U.S. economy. (Those comments would seem to vindicate those betting the slide will continue.) And Commerce Secretary Wilbur Ross fanned talk of trade wars, saying to expect more measures to defend U.S. commerce, a message Trump is expected to underscore.

State tax workarounds could cost the Treasury $154 billion. Five Democratic-leaning states exploring ways to change their tax laws could remove roughly that much from federal coffers over the next eight years. The potential revenue hit reflects a furious burst of creativity among state lawmakers and tax experts in response to Republicans’ tax overhaul. Some states are exploring getting around new limits to state and local tax deductions by switching from a personal income tax to an employer-paid state payroll tax, which employers could deduct fully on their federal returns.

So much for former Brazilian leader Lula’s hopes for a comeback. An appeals court unanimously upheld his corruption conviction, likely preventing the 72-year-old former president and current presidential front-runner—who maintains the charges were politically motivated and can appeal again—from running this year. The decision could have big repercussions for Brazil’s economy; Lula had promised, if elected, to roll back market-friendly reforms, and in the wake of the judges’ ruling, Brazilian markets soared to a record.

Pioneering travel outfitters are spanning the gap between cultures in a new way—by encouraging travelers to break bread with locals on both sides of the unofficial border. Tour-group operator Intrepid Travel’s trips begin in Tel Aviv, the restaurant capital of the Middle East, and end in Jerusalem, where travelers check out religious sites before tucking into bowls of hummus. In between, they take guests to an Israeli winery near the Negev desert, a Palestinian bakery in Nablus, and a cooking demonstration in an Arab village.
