Trump is not a Russian Asset. After Joe Biden gave Ukraine's soldiers Training, Weapons, Tanks, Jets and Long Range Missiles to Bomb Russia, the Russians decided enough was enough and they were going to NUKE Ukraine. Trump, realizing that this was A BAD IDEA decided that he wanted no part in Nuclear War and therefore he backed down. Trump stood by while Ukraine carried out an attempted assassination of Putin last year, which further soured US - Russian relations.
So the idea that Donald Trump is a Russian asset is somewhat, not correct.
