I couldn't tell you what his wife did to be sanctioned so there's not much info on that besides the tweet.

On the journalist himself there's this article showing how the EU along with Zionist ran German media sanctioned him for spreading "Hamas propaganda".

EU sanctions German journalist in shocking first over Gaza reporting

He's a German citizen that was accused of "Russian misinformation", which these days means any criticism of EU actions:

Doğru has consistently opposed Russia’s invasion of Ukraine, a stance he reiterated in public statements. However, his critical reporting on German domestic policies, particularly the suppression of Palestine solidarity actions, drew scrutiny from mainstream media and officials.

The EU rationale links these actions to Russian interests: By amplifying narratives critical of Western policies (e.g., support for Israel or repression of protests), Doğru is said to indirectly aid Moscow’s efforts to sow division in Europe.

Maybe the EU shouldn't be doing the things that are sowing division?? Maybe the criticism is grassroots and not funded by Ruzzia??

So his accounts were frozen in retaliation, and now his wife's accounts were also frozen due to a shared car insurance. It is the typical silencing of critics that Francesca Albanese is also subjected to.

Sadly this is EU wide sanctions. The entire EU apparatus has come together to sanction people who speak up against genocide.

That said, the campaign against the journalist was very much done by Zionist propaganda outlets and politicians in Nazi Germany in a coordinated Nazi blood libel campaign.
