A nonpartisan newspaper could also condemn or blame a political party for an action. But if all of its posts were supportive of one administration, it would no longer be partisan.

You can just look through the old white house accounts. For example this tweet https://x.com/WhiteHouse46/status/1879171105044181097 , "While Congressional Republicans refused to pass a bipartisan border security agreement, President Biden took action and encounters today are the lowest since July 2020."

Looking through the tweets, you'll see it's not nonpartisan and isn't supposed to be.
