President-elect Donald Trump looped in Elon Musk on his phone call with Ukraine’s President Volodymyr Zelenskyy on Wednesday, according to Axios.

As one of Trump’s top campaign donors, Musk has forged a strong alliance with the incoming president. The Tesla CEO has been rumored as a candidate for a position in Trump’s cabinet, and his involvement on a key foreign policy call makes Musk’s potential appointment seem more likely.

According to the report, Zelenskyy was encouraged by how soon Trump contacted him after his victory in the presidential race. Zelenskyy echoed this sentiment on X. Trump has had a close relationship with Russia’s president, Vladimir Putin, but sources told Axios that the call “didn’t leave Zelenskyy with a feeling of despair.” However, it’s still unknown what actions Trump will take regarding the war between Russia and Ukraine.

As for Musk, the tech mogul reportedly told Zelenskyy that he will continue providing Starlink satellites to Ukraine; however, Musk has mocked the Ukrainian government in the past for asking for aid.
