At least for the US, the Federal Register would be a good place to start if you're not scraping it already: https://www.federalregister.gov/developers/documentation/api...

Federal news radio: https://federalnewsnetwork.com/

Government procurement announcements and opportunities: https://sam.gov/reports/awards/standard

In general, you might get more traction if you tilt this toward government contract capture a la Deltek GovWin and other companies. Lots of money in contract intelligence as well as proposal support (in addition to government relations / lobbying)
