The issue itself may not be partisan, but it will still be interpreted that way. The media has been a political strawman for both parties for a long time. Each accuses the other of essentially controlling it to further their agenda. Once accusations of 'treason' are made from a media source, then inevitably at least half of the country will dismiss it as propaganda.

If a media outlet did, I think they would probably have to do so carefully.

It's the CIA looking at activity logs on CIA servers, to monitor what Senate users were doing, so they could interfere with the things the Senate found.

It's shady, and likely illegal, but it's not quite hacking, and it's definitely not hacking the senate.
