One of Ukraine’s most popular TV channels 1+1, owned by oligarch Ihor Kolomoisky, has given Zelenskiy a powerful platform in recent months during his meteoric rise to the brink of the presidency.

On Saturday, a day before Zelenskiy won the first round of the presidential contest and set up a run-off with the incumbent Petro Poroshenko, 1+1 filled its schedule with back-to-back shows by the comedian and actor.

The fact that Zelenskiy is a major star on the channel has stoked worries among some investors and voters, and accusations from his political opponents, that he is in the pocket of Kolomoisky.

just reading a few paragraphs from this one, this kinda jumped out:

On 25 March 2014, Rabinovich registered with the Central Election Commission as a self-nominated candidate for the presidency of Ukraine. This was partly to counter the characterization of the new Ukrainian government as antisemitic. After registering, Rabinovich said: "I want to destroy the myth about an anti-semitic Ukraine which is spreading around the world. Probably I'm the most fortunate candidate. Today unification is needed, and I'm a unifying candidate. I have no maniacal thirst for power, I just want to help the country". In the election, he received 2.25% of the vote, with his best showing in Dnipropetrovsk and the Zaporizhzhia, Mykolaiv and Odesa oblasts. Rabinovich was elected to the Verkhovna Rada (Ukraine's parliament) the same year, placing fourth on the pro-Russian Opposition Bloc's electoral list.

On 14 February 2022, Rabinovich published a post on Facebook, stating that "the war has started" and blaming the West and Ukraine for it. Following the start of the 2022 Russian invasion of Ukraine, he left Ukraine and fled abroad.
