Rosie O'Donnell Questions Our Photog While Staying Mum On Melania and Barron

Rosie O'Donnell clearly did not want to talk about her comments about Barron Trump or her apology to the 10-year-old and his mom, Melania ... but boy did she have questions for the photog.

Rosie arrived at LAX Thursday and shut down when the photog asked about her walk back over her tweet that Barron might be autistic. He's not, and Melania was pissed.

You gotta hand it to her ... Rosie used her interviewing skills -- clearly from her talk show -- to adroitly deflect questions from the terminal to her waiting SUV.
