JFK met with Khrushchev. Bush Senior and Reagan had regular contact with Gorbachev. It's not weird for heads of state to talk to each other.

What's weird is for Trump to be paying tax dollars to cancel energy projects because he doesn't like windmills or using the FCC to investigate media outlets who criticize him.

There are plenty of good examples to use that it makes no sense to resort to evidence-free innuendo.
