With the New York City Democratic mayoral primary race entering the homestretch, several candidates took advantage of the Juneteenth holiday to step up attacks on their opponents.

New York City Comptroller and mayoral candidate Brad Lander was detained for several hours after being arrested at an immigration court on Tuesday, the latest politician opposed to U.S. President Donald Trump's immigration raids to get caught up with law enforcement.

Waymo says it wants to bring driverless cars to NYC, but state law requires a trained specialist behind the wheel.

Alphabet's self-driving unit Waymo said on Wednesday its vehicles will be back in New York City next month for autonomous testing, as it continues to scale operations in the U.S.

But it won’t be offering rides to the paying public yet, as it currently does in four other cities. The company announced Wednesday that it has applied for a permit with the New York City Department of Transportation for its vehicles to operate autonomously with a “trained specialist” behind the wheel in Manhattan.
