All it takes is staff or interns to compromise an entire political campaign. Just because they aren't the primary candidate doesn't mean they don't have access via blackmail to the information someone is looking for. It really is a huge security nightmare with people that have a candidate's calendar or even access to a candidate's email. Also, in terms of Trump possibly being compromised. Google Jeffrey Epstein.
To be clear, I do not have any illusory perception of the personal morality of Trump, it's just that location data isn't enough to really tie anyone to any official or important person. You can just claim it was an intern even if it was the politician was the user and fire the intern. My point is it's not as potentially damaging as say actual evidence of scandalous behavior is.
For example, there was the comedic Ted Cruz twitter scandal in which his account liked a pornhub video featuring incest play. He claimed it was a staff mistake and moved on.
