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.
