As we know Donald Trump has a cozy relationship with the Russian strongman Vladimir Putin.
So cozy in fact that the Obama administration has accused the Russians of trying to influence the result of the American election.
The Obama administration on Friday formally accused the Russian government of stealing and disclosing emails from the Democratic National Committee and a range of other institutions and prominent individuals, immediately raising the issue of whether President Obama would seek sanctions or other retaliation.
But this is the absolute limit.
