Facebook has suspended Strategic Communication Laboratories (SCL) and its affiliate, data analysis and targeting firm Cambridge Analytica, for "violating our platform policies."

Why it matters, per Axios' Kim Hart: Cambridge Analytica, a data analytics firm that worked with the Trump campaign leading up to the 2016 election, claimed to have developed personality profiles on every American — but it's unclear where that data came from. It has become a focus of both the House Intelligence Committee’s investigation into Russian election meddling and Robert Mueller’s probe.

  • Per Facebook, a University of Cambridge psychology professor named Dr. Aleksandr Kogan passed user information collected through an app that used Facebook Login to the organization.
  • While his data collection was "legitimate," he violated Facebook's policies by "passing information on to a third party." Facebook then "demanded certification from Kogan and all parties he had given data to that the information had been destroyed."
  • Facebook said it was told "several days ago" that not all of the data collected by Kogan had been destroyed, leading to the suspension of SCL/Cambridge Analytica, Kogan, and a third person who was given the data.
  • "We are moving aggressively to determine the accuracy of these claims," said Facebook's Paul Grewal in a blog post that went live late Friday evening.

A major winter storm was lashing much of the East Coast on Sunday, causing widespread power outages and disrupting travel over the holiday weekend.

The big picture: Heavy snow and ice accumulations are "likely to produce hazardous travel," downed trees and more power outages from the Mid-South to the Northeast, per the National Weather Service. Some parts of the U.S. can expect to see up to a foot of snow through Monday.

Significant damage has been reported in Tonga following an undersea volcanic eruption on Saturday, which covered the Pacific nation in ash and cut off communication lines.

North Korea's military fired "two suspected short-range ballistic missiles" eastward from Pyongyang on Monday morning local time, per South Korean and Japanese officials.

Why it matters: The fourth such launch since Jan. 5 comes days after North Korea's military warned of "stronger" action if the U.S. moved to have more sanctions imposed on the country.
