NO, its called a President doing his JOB..all President elects have done it..Obama had his goons contact IRAN while still running for President, he was still a candidate in 2008, wasn’t a crime for him..Bush did it, Reagan even had his team contact other nations..its what Presidents do Trump was getting to WORK good for him!
I think Trump was worried that Obozzo would play a scorched earth policy during the transition.
Stirring up nuclear war with Russia, abandoning Israel and giving succour and encouragement to evil nations.
As a patriot, as a man of human decency, it was absolutely necessary for Trump to communicate a true American message to all nations.
