Politician Parade adds a state’s Congresspeople to your Google News search. Depending on how many reps your state has, this tool will generate one or more URLs with your query AND your Congressional representatives added as an “or” array.
It doesn’t work as well as I’d prefer; results can get cluttered. I’m probably going to add filters for seniority and how recent the news should be.
You’ll need an API Key to use this tool. You can get them free from https://www.propublica.org/datastore/api/propublica-congress-api .
