After the disastrous ‘summit’ in Alaska it looks like Trump is looking for someone to throw under the bus. Secretary of State, Marco Rubio, looks like the prime candidate.
Rubio sold his soul to work for Trump. Now he is suffering the consequences. The problem: Trump is a Russian asset, Rubio is not. Marco is now having to bite his tongue in order to keep his job.
Trump wants to sell out Ukraine. Is Rubio willing to join in on the backstabbing? Not sure.

At one time Rubio supported Ukraine’s fight against Russia. Not anymore.
