Earlier in the same interview he's explicitly asked if he wants to apologize to Trump and says "no." Possibly a real-time softening but also "sorry for this [situation]" not really being the same as an apology.

I wouldn't be very surprised if there was some thaw in relations that comes with an apology, smiling and making nice for the cameras. But I wouldn't be at all surprised at the reverse, particularly considering that Trump tendency to come down in Putin's corner.

Trump should apologize and probably resign while we are at that. But the conservatives want all the good old times without the honor code that existed to some degree back then.
