Lest we forget, he's also been big on the Cuba deal.

Despite this, I don't think there have been outright hostilities with Marco Rubio, I mean, it appears they've still been friends. Just because one sees things differently doesn't mean you can not have a cordial relationship with them.

Menendez, for how much maligned he is, especially rightfully on domestically, is right about Cuba and right on a number of other foreign policy issues, imho. Menendez is sort of a hawk. That's a bit off topic but shows, on this single issue of Cuba, the D does better.
