What government are we talking about? The U.S. Federal government? And which parts? FBI? CIA? NSA? Or the State government? Or the Winchester County government?
Or all of them?!
And what about foreign nations? Can they access these portals as well?
Any government can submit a request or a subpoena to any commercial company in any country. That company might comply, demand a formal subpoena, or oppose the subpoena in court. An international company can choose to leave a country if it thinks that its presence poses a legal risk.
That portal is just to smooth things out when many requests are coming in and avoid confusion. This leak is about DHS, but every law enforcement agency in the US (including local sheriffs) has access to a secure interface to ask for certain things — access to the account of a missing teenager is a classic case for local LEO. Company lawyers use that portal to push back against excessive requests.
It’s just more secure than email accounts that are the best tech too many police departments have and that were spoofed a couple of years ago as part of a wider security scandal.
