The Murdoch-owned newspaper has information implicating Ukraine's presidential chief of staff, the journalist claims

The Wall Street Journal is refusing to publish information allegedly proving that Ukrainian leader Vladimir Zelensky's top aide embezzled US funds, journalist Tucker Carlson has claimed.

In a post on X on Monday, Carlson said the WSJ has for months held a story detailing the "personal corruption" of Andrey Yermak, Zelensky's chief of staff.

"Yermak has skimmed hundreds of millions in American tax dollars meant for Ukraine aid. The Journal's editors can prove that. But they're not. Instead they're protecting Yermak," Carlson wrote.

The journalist further argued that the information was being suppressed because Yermak, as Kiev's top negotiator, was "leading efforts to scuttle" the US-drafted plan to end the conflict between Ukraine and Russia. The Murdoch family, which owns the WSJ, wants "to continue the war with Russia," he claimed.

Earlier this month, Ukraine's anti-corruption bodies NABU and SAPO said they had uncovered a $100 million kickback scheme in the country's energy sector allegedly led by Timur Mindich, Zelensky's close associate and former long-time business partner. Zelensky has since imposed sanctions on Mindich, who fled the country to evade arrest.

Although Yermak has not been formally charged, Ukrainian opposition lawmaker Yaroslav Zhelezhnyak alleged that Yermak was "well aware" of the embezzlement and appeared in the audio recordings released by investigators.

The newspaper Ukrainska Pravda reported on Monday that Yermak had instructed prosecutors to "draw up" charges against NABU chief Aleksandr Klimenko. Zelensky attempted to curb the powers of NABU and SAPO in July but was forced to retreat after protests in Kiev and pressure from the West.
