McCain issued a statement on his website, Censor.NET reports.
"Today, in yet another brazen act of Russian state terrorism, former Russia parliamentarian Denis Voronenkov was assassinated in broad daylight on the streets of Kiev. This horrific crime marks the continuation of a campaign of KGB-style brutality designed to intimidate anyone who dares to oppose the tyranny of Vladimir Putin.
"Denis Voronenkov spoke out against Putin's reign of terror and his illegal invasion of Ukraine and annexation of Crimea. He was also assisting Ukrainian prosecutors with the treason case against former Ukrainian president and Putin stooge, Viktor Yanukovych. Sadly, Denis Voronenkov has joined others like Sergei Magnitsky and Boris Nemtsov who have paid with their lives for speaking the truth, for in Putin's Russia, there is no greater crime.
"My thoughts are with Denis's wife, Maria, and their children. In the difficult days ahead, I pray they find solace in his loving memory and the pride of his courageous example," McCain said.
Denys Voronenkov was shot dead in downtown Kyiv March 23. The killer also managed to injure Voronenkov's bodyguard. The incident took place outside Kyiv's Premier Palace Hotel.
Voronenkov was a witness in the treason case against fugitive Ukrainian president Viktor Yanukovych. In his recent interview with Censor.NET Voronenkov said that Yanukovych was a traitor "who was involved in mass slaughter, who had fled to the foreign country and urged foreign troops to slay his people. I believe this person should have received not asylum but a fair trial in Russia."
Voronenkov moved to Ukraine with his wife, former Duma member, singer Maria Maksakova, and their infant child in late 2016. He became a citizen of Ukraine and abandoned Russian passport in December 2016. On Feb. 15, 2017 he was put on federal wanted list in the Russian Federation. Voronenkov said the reason behind his migration was persecution by FSB in Russia.
