It is a bit odd from my perspective because I have not seen/heard of "Axios" until this "Trump Interview" thing happened. So I understand the OP's bafflement at it's prominence all of a sudden. Even the fact that they got an interview with the US president seems out of place to me.
I've been reading the site regularly for a few years and seen them (often Swan) break a lot of Inside Baseball type stories on the White House, which I take to mean that they have some pretty high level sources.
They also do occasional stories that look like obvious beat-sweateners[0], likely to keep that access flowing.
Overall I'd say it's a pretty good source for non-partisan news.
