Republican Senator Kennedy lashed out at Putin over Trump

"He has reneged on all the promises he made to President Trump. His latest offer is, well, nothing. He wants to keep all the territory he took," Kennedy said.

He also believes that Putin thinks the US is afraid of Russia.

He has fooled President Trump at every turn. He has disrespected our president. I don't think things will get any better until we make it clear to Mr. Putin that we are prepared to turn him and his country into fish food.

The politician emphasized that Russia must be "pressed and suppressed" or it will not come to the negotiating table. He also added that Europe must do more when it comes to defense spending.

On April 26, US President Donald Trump, after a personal conversation with Ukrainian President Volodymyr Zelenskyy during the funeral of Pope Francis, issued a statement sharply criticizing Kremlin leader Vladimir Putin.
