Almost half of the almost $3 billion spent online this Thanksgiving came from mobile devices, according to Adobe Analytics, with mobile making up 61% of site visits.

Why it matters: Brick-and-mortar stores have taken a hit this year, but the growing popularity and user-friendliness of mobile shopping could maintain the retail success of Black Friday deals. Adobe found a 51% increase in mobile sales on Thanksgiving from last year, and overall retail sales are projected to rack up to $20 billion by the end of the weekend.

Experts say: "On both Thanksgiving and Black Friday, the gap between mobile traffic and revenue is closing. Shoppers looking for discounts are getting better at using smartphones to quickly close the deal, and we are seeing better mobile conversion this season at over 10% growth," Adobe vice president Mickey Mericle told Retail Dive.

President Trump signed an executive order on Monday that would impose sanctions on any person or entity that contributes to the supply, sale, or transfer of conventional arms to or from Iran or is engaged in providing training and financial support related to those weapons.

Why it matters: The executive order is the first step by the Trump administration to put teeth into its claim that international sanctions on Iran were restored over the weekend, one month after the U.S. initiated the "snapback" process under a United Nations Security Council resolution.

CDC says it mistakenly published guidance about COVID-19 spreading through air

The CDC has removed new guidance that acknowledged airborne transmission of the coronavirus, posting in a note on its website that the guidance was only a draft and had been published in error.

Why it matters: The initial update — which was little noticed until a CNN story was published Sunday — had come months after scientists pushed for the agency to acknowledge the disease was transmissible through the air. The CDC previously said that close person-to-person contact was the bigger concern, and the language has been changed back to erase the warning about airborne transmission.
