We’re not sure where this inquiry is headed, but these characters could light the way.

The impeachment train has left the station. While Speaker Nancy Pelosi’s declaration last week that the House would move forward on an impeachment inquiry lacked legislative substance, it served to set in motion a targeted inquiry into whether President Donald Trump abused the power of his office in trying to get the government of Ukraine to help his campaign.

Thursday’s House Intelligence Committee hearing with Acting Director of National Intelligence Robert Maguire was just the start. No one is sure where this process will go in the coming months, but here are five people we’d be interested to see in the witness chair — and what they might offer.

The German auto giant’s Wolfsburg plant, the world’s largest factory, produces many more wursts than cars.

While thousands of cars roll off the production lines at the headquarters of Volkswagen each day, a group of German butchers huddles around a table at lunch to carefully inspect, smell and taste test a different product: the day’s freshly produced currywurst sausage.

Currywurst — essentially a grilled bratwurst smothered in a mix of ketchup and curry powder — is one of Germany’s most popular foods, and at Volkswagen canteens in the northern German city of Wolfsburg in the state of Lower Saxony, that holds particularly true. At 70 million square feet, the Wolfsburg plant is the largest factory in the world, with 60,000 employees. So big that an internal butchery churns out 6.7 million Volkswagen-branded currywurst sausages annually. In fact, the Wolfsburg factory produces eight times more currywurst than cars.

Andrew “Nasher” Telfer’s live video games and trick shot videos have made him a star — and brands want in.

Andrew Telfer and his wife, Mel, just moved into a new house. But one key renovation is still needed.

“I get a little bit too hyped, screaming at a nice goal,” he says. “Then I wake her and that’s not the best. I’m working on soundproofing my basement.”

Telfer, 25, is better known as “Nasher,” hockey influencer extraordinaire. And by “nice goal,” he is talking about his virtual skills.
