While Amazon provides UPS, FedEx and USPS with huge business, it is silently collecting mountains of data on the logistics industry through the movement of its own packages.

Why it matters: Amazon already has its own fleet of trucks and planes for some deliveries. With its data stash, it could soon get smart enough to eat the big shippers' lunch.

How it works: Amazon does not decide how a package will be shipped until it gets to the final station within a warehouse (photo above).

  • At that point, Amazon’s own optimization system decides which carrier will take the box based on factors like where it’s going, how big it is and how much space is available on a given truck.

After making billions of decisions about how to ship packages to get them delivered as fast as possible, Amazon has insights any of the big shipping players would want. And it is using them to make its own shipping services sharper.

  • Scott Anderson, director of Amazon Robotics Fulfillment, told me his team regularly shares findings on shipping with Amazon Logistics. "There's a feedback loop," he said.

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.

Trump says he doesn't know who Proud Boys are after telling them to "stand by"

President Trump told reporters on Wednesday that he doesn't know who the "Proud Boys" are, after saying at the presidential debate last night that the far-right group should "stand back and stand by" in response to a question asking him to condemn white supremacists.

Why it matters: The comments set off outrage and calls for clarification from a number of Republican senators. After being asked several times on Wednesday whether he will condemn white supremacy, Trump responded: "I have always denounced any form — any form of any of that, you have to denounce. But I also — Joe Biden has to say something about antifa."
