The new USA 118th Congressional District features have been recently published. These layers are updated at least twice a year. Two iterations are available, one focused on the U.S. and the other including overseas territories. View the item details below:
USA 118th Congressional Districts (all territories)

Question, what would be a good way for an organization to stay up-to-date with the Esri-produced Congressional Districts?
Right now, we could check Living Atlas daily around the beginning of the new congressional session, would you have any suggestions or does the Living Atlas have an RSS feed to follow?
Additionally, what's the update schedule look like for Living Atlas layers to appear in ArcGIS Pro?
You will always be up-to-date with the congressional districts, but it might not seem like you are if you are using ArcGIS Enterprise.
Pro does not have it's own Living Atlas content, rather it accesses Living Atlas from what is in your ArcGIS Online organization or configured in your Enterprise. For Enterprise Living Atlas items, they are pre-installed with Enterprise (for many reasons) but point to existing Living Atlas REST endpoints.
The congressional districts are overwritten as they are updated and the item ID and the REST endpoints never change. So while you see 117th congressional districts, you are actually pointing to the 118th congressional districts. That's an artifact due to the Living Atlas items being "installed" in your Enterprise. The next time you update Enterprise you will see the change to 118th. But since that particular service is overwritten, it's actually the most current.
The congressional districts are updated whenever this document is updated: https://clerk.house.gov/member_info/olm-118.pdf
And though the item details state 2x per year, the frequency is typically more like 3-4x per year.
Another thing you can do is instead of searching for Living Atlas content from Pro, in Pro you can search ArcGIS Online for the 118th districts and compare. Anything in Living Atlas that is public, non-subscriber content (like congressional districts are) can be discovered when searching ArcGIS Online since it is all part of the same public ecosystem (and if your Enterprise organization is setup to allow that).
So a few things here:
In the images below the black lines are sourced directly from the link above (118th Congress)EDIT:These are the two services that I was able to find, is there a 3rd service endpoint that is just the current data then?https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_117th_Congressional_Districts/FeatureServerhttps://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_118th_Congressional_Districts/FeatureServer
I'm also very confused as to why the sourcing of the Living Atlas layer would be different depending on which tool you use (Catalog Pane vs. Add Data).
My humblest apologies for presenting incorrect and confusing information. The majority of Living Atlas content is overwritten, so once you add a Living Atlas layer to your map you're always looking at the latest and most up-to-date data available (think Live Feeds - same layer, updated frequently).
I was mistaken that the congressional districts worked the same way, and indeed they do not. Apparently by customer request, they are archived and there is a new service published for each new congressional district. You'll see that in the services directory the previous congressional districts are still available.
That said, when updates happen to a particular congressional district (e.g., the 118th), the previous 118th district information is overwritten.
I'll use the words "ArcGIS Online Living Atlas" and "ArcGIS Enterprise Living Atlas" to articulate the differences and what is going on.
In ArcGIS Online Living Atlas, you only find the latest congressional district layer. In Enterprise Living Atlas, you will see what is in your Enterprise installation. This is because for Enterprise, a subset of Living Atlas item cards are installed. These have the same item ID as in Online Living Atlas, and point by reference to the same service. But that is why in Online Living Atlas you can find the 118th congressional districts, and in your Enterprise Living Atlas they are not found. When you update Enterprise next, you will see that new item.
On top of that, anything in Living Atlas is part of the Online ecosystem. So that is why if you search ArcGIS Online in Contents for "118th congressional" you will find it, or in Enterprise Map Viewer if you search ArcGIS Online (not Living Atlas) for layers, you will find the 118th as well (depending on how your admin has set things up).
