Investigators will look into whether Meta has failed to mitigate risks as it looks to discontinue CrowdTangle, a tool that shows publishers how content is spreading across the site, and to outline concerns related to how Meta tracks disinformation to help fact-checkers and journalists.

The commission is expected to give Meta five working days to say what it will do to mitigate the situation or threaten the social media group with measures under the DSA, the people said.

There is no set deadline for the investigation to end and it will depend on Meta’s willingness to cooperate, the EU is expected to say.
