President Donald Trump says his administration has already had “very serious” discussions with Russia about its war in Ukraine and that he and Russian President Vladimir Putin could soon take “significant” action toward ending the grinding conflict.

Volodin said merely discussing a plot to assassinate Putin was path to nuclear war and that Carlson's comments should be investigated further. State news agency Tass reported that Russia's parliament will appeal to U.S. Congress and the U.N. to investigate the claims.

Trump's Ukraine envoy said Sunday that both Kyiv and Moscow would have to make concessions if they are to successfully negotiate a solution to the ongoing war.

The President of the United States, Donald Trump, announced on Friday that he is engaging in talks with Russian President Vladimir Putin. He mentioned that they "will do something significant," although he did not provide specifics.
