The corresponding verb 'twittern' (to tweet) is derived from the noun 'der Tweet' (the tweet). It describes the action of creating and publishing a tweet.
Viele Journalisten twittern live von den Veranstaltungen.
Many journalists tweet live from the events.
Certain verbs are often used with 'Tweet' to describe how people interact with it. Common combinations are 'einen Tweet absetzen' (to post a tweet), 'einen Tweet veröffentlichen' (to publish a tweet), or 'einen Tweet löschen' (to delete a tweet).
Nach der Kritik hat der Schauspieler seinen Tweet wieder gelöscht.
After the criticism, the actor deleted his tweet again.
The prepositions 'in' and 'per' are used differently. 'In einem Tweet' (in a tweet) describes where the information appears, while 'per Tweet' (by tweet / via tweet) describes how the information is transmitted.
In seinem Tweet kritisierte er die Regierung scharf.
In his tweet, he sharply criticized the government.
message / news
'die Nachricht' and 'der Tweet' can both be a short message. 'Nachricht' is general and can come orally, by text message, by email, or in a messenger app. 'Tweet' is much more specific: it is a short public message on the platform X, formerly Twitter. The words can be confused because a tweet is also a kind of message. But not every message is a tweet. If the platform X is not relevant, 'Nachricht' is more natural. If you mean exactly this social media format, 'Tweet' fits.

Der Politiker löschte seinen Tweet, weil viele Leute kritisch reagierten.
The politician deleted his tweet because many people reacted critically.
