A new type of police dog — "explosive odor-pursuit dogs” — are trained to pick up the scent of a bomb hundreds of feet away and then lead their handlers to the source, the N.Y. Times' Ashley Southall reports:

How it works: The dogs "are asked to intercept suicide bombers and other terrorists before they reach targets like concerts, parades and sporting events."

The odor-pursuit dogs, which cost about $50,000 each, "are drawn from pointy-eared breeds like German shepherds and Belgian Malinois, whose traits dovetail with the job. They can pick up scents at longer ranges than other police dogs, and will start a search without waiting for their handlers’ directions."

  • "The handlers give them commands in Dutch, Czech and Slovak, in a nod to their origins: The dogs are bred in the Netherlands, the Czech Republic and Slovakia."
  • "The new dogs have a longer range of smell than ... Vapor Wake dogs, which detect the smell of explosives on people near them. Those dogs are primarily Labradors, whose friendly nature allows them to work in crowds."

Senate Democrats block vote on McConnell's targeted COVID relief bill

Senate Democrats on Wednesday blocked a vote on Republicans' $500 billion targeted COVID-19 relief bill, a far less comprehensive package than the $1.8 trillion+ deal currently being negotiated between the Trump administration and House Democrats.

Why it matters: There's little appetite in the Senate for a stimulus bill with a price tag as large as what President Trump and House Speaker Nancy Pelosi have been calling for. Senate Majority Leader Mitch McConnell's (R-Ky.) "skinny" proposal was mostly seen as a political maneuver, as it had little chance of making it out of the Senate.

The hazy line between politics and influence campaigns

The recent firestorm over the New York Post’s publication of stories relying on data from a hard drive allegedly belonging to Hunter Biden shows the increasingly hazy line between domestic political “dirty tricks” and a foreign-sponsored disinformation operation.

Why it matters: This haziness could give determined actors cover to conduct influence operations aimed at undermining U.S. democracy through channels that just look like old-fashioned hard-nosed politics.
