Summary

What we are after:
On June 14, FEC issued FR notice of interim final rules on IEs. We need to do the routine work of updating the regulations page and the E&J pages.

Completion criteria

• Pending rulemaking matters page is updated (will need to be switched back after 9/30
• FR notice (using SERS link) is added to https://www.fec.gov/legal-resources/regulations/ under "Changes not included in 2022 edition"
• FR notice (using SERS link) is added to the chronological index and to the citation indexes for the regulations mentioned in the notice.
• Work is demo'ed for Info and content team.

This has been completed. Demonstrated for Kathy. Process for E&Js is documented in a Content team how-to guide.

Because this was an interim final rule that requested comments but also takes effect on a future date, it got added in multiple spots.
