Trump Puts ‘Extreme Vetting’ to the Test

Donald Trump has two new words for you: “extreme vetting.” That’s how he described the latest twist to his immigration policy, which would include an ideological test that he compared to Cold War-era screening. “Those who do not believe in our Constitution, or who support bigotry and hatred, will not be admitted,” he said. What could that mean in practice? Read on.

The Year of the Wildfire

After years of drought, California has seen wildfires already burn more than 360 square miles and destroy more than 400 homes and other structures in 2016. The latest devastation: Lake County in Northern California, where residents were just starting to recover after a series of blazes last year. Now, authorities have arrested a man on suspicion of arson in connection with multiple fires in the area. But here’s why little relief is in sight throughout the state.

Why Milwaukee Broke Out in Violence

When protests over a police shooting in Milwaukee turned violent, Reggie Moore, a black man who was appointed by the mayor to lead the city’s Office of Violence Prevention, wasn’t surprised. “What’s happening isn’t random,” he said. “Last year, we saw a spike in homicides. There is job loss. There are bad schools. There are a lot of teens in this neighborhood who feel like they aren’t getting their fair share.” Take a closer look at the decades of racial tensions and grievances that led up to this weekend.

The Nixon Library Vows No Cover-Ups

When the Richard Nixon Presidential Library opened 26 years ago in Yorba Linda, many historians dismissed it. After all, Nixon himself had approved its Watergate exhibit. But a lot of that began to change in 2007, after it entered the official presidential library system under the National Archives. Now the museum is getting a $15-million makeover, with the goal of giving an unflinching but well-rounded picture of the disgraced 37th president. Take a hardhat tour here before it reopens in October.

Is That an Electric Scooter on Rio’s Cycling Track?

The bicycle race known as keirin got its start in the late 1940s, thanks to Japanese gamblers. For those who may have never heard of it, it’s somewhat like NASCAR on two wheels. A rider on an electric scooter serves as a pace car, starting at about 15 mph and gradually accelerating to 30 mph. That’s when it leaves the track, and the field really takes off. “You’re talking about top speed, and you’re allowed to bump each other,” says one rider. “It’s pretty much the worst of all situations.”

ONLY IN L.A.

In Pacific Palisades, there’s a storied house from 1941: Exiled German author Thomas Mann and his wife, Katia, commissioned it from architect J.R. Davidson, and Mann wrote the novels “Doctor Faustus” and “The Holy Sinner” there. Now, you can buy it for a cool $15 million — but it’s being marketed as a tear-down, with no mention of its history. Architecture critic Christopher Hawthorne takes a closer look at its significance.
