Rosie O'Donnell Says Barron Trump Controversy Overblown, Slams President

Rosie O'Donnell firmly believes the Stanford Law Professor who name-dropped Barron Trump didn't do anything wrong and hopes the testimony helps impeach the President.

We got Rosie and her BFF Ally Sheedy Thursday night outside the "Jagged Little Pill" musical in NYC and asked her about the GOP outrage over Prof. Pamela Karlan's wordplay. Not shockingly ... Rosie's team Karlan, all the way.

She says Karlan made a fair point about POTUS, and it's being taken out of context to look malicious. Both Rosie and Ally think there was nothing mean spirited about it. Rosie thinks it's nice Karlan apologized but adds ... it wasn't necessary.

Rosie, of course, had her own controversy involving the President and Melania's son a few years back, when she posted a video questioning whether Barron was autistic.

She apologized to Melania for being insensitive and causing pain ... but clearly thinks Karlan's case is different.

As for the impeachment hearings, in general, Rosie admitted she's a total junkie. It's no secret she has a rooting interest and spells out the many reasons why she's on Karlan's side.
