In the next few weeks, Instagram will stop allowing influencers to promote tobacco, weapons or vaping products in branded posts, it announced in a blog post on Wednesday.

Why it matters: It's the first time the photo app is establishing boundaries for influencer sponsored content.

Facebook policies prohibited ads for weapons, tobacco and vaping products on its feeds, and until now, Instagram allowed private users to post paid promotions of these products without the oversight of Facebook's ad-buying system.

  • "Instagram reaches a younger demographic, which may be more easily swayed by ads from the famous users of the platform," per Bloomberg.
  • Facebook tells CNBC that the company is building tools to help content creators comply with new policies, like the ability to restrict which users can see their content based on age.

What's next: Starting next year, Instagram will restrict the audience for influencer ads involving alcohol and dietary supplements.

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.
