Deutsche Bank. North Korea’s hacking of Sony Pictures. The House Intelligence Committee’s investigation of President Trump. In each of these cases, Val Broeksmit, above, has taken his secret documents — and uncanny addiction to drama — to the center of the news, dangling files in front of journalists and investigators.

Mr. Broeksmit, an unemployed rock musician, has been an important, often maddening, source for our finance editor, who writes: “We might wish our whistle-blowers were stoic, unimpeachable do-gooders. In reality, to let you in on a journalistic secret, they’re often more like Val Broeksmit.”

Here’s what else is happening

U.S. Border: President Trump suggested that soldiers shoot migrants in the legs to stop them from getting away, and he told advisers that he wanted a moat filled with snakes or alligators around the border wall with Mexico.

Harvard: A judge ruled that the university does not discriminate against Asian-American applicants in its use of affirmative action, upholding a system of race-conscious admissions used by colleges across the country to create a diverse student body. The decision will be appealed and may end up in the Supreme Court.

BBC: The news outlet reversed a decision that the television anchor Naga Munchetty had breached editorial standards by criticizing President Trump’s comments.

Credit Suisse: A spying scandal at the Swiss bank led to the resignation of its chief operating officer, Pierre-Olivier Bouée, who had ordered surveillance of a wealth manager when he quit to work for UBS.

Peru: The country plunged into the deepest political crisis in decades, with both the president and the vice president claiming to be the country’s rightful leader, and Congress closed and surrounded by riot police officers.
