This reads like your CEO is mixing an argument against serifs with an argument against Times specifically. Later on they make a case against Times' lack of support for more modern features in digital fonts, which is a fine argument, but a question comes to mind: is the solution a sans-serif font?
It seems to me upon reading the article that Rubio's staff, or Rubio himself, is being overly specific with the font and I suspect that, being uninformed, what they really want is a serif font rather than Times New Roman, specifically. Maybe I'm wrong.
In any case, I'd like for you/your CEO to make it clearer, if you will: do you believe official government communications should use a sans-serif font altogether or is it just a problem with Times? Or both?
On a more personal note, is there any serif font you'd suggest as an alternative?
Thank you. (And sorry if I read this wrong.)
