John Stamos, Jodie Sweetin's Reaction to Lori Loughlin Indictment

Lori Loughlin's "Full House" and "Fuller House" co-stars John Stamos and Jodie Sweetin are rallying around her ... in maybe the only way they can for now on the heels of her indictment in the college bribery scandal.

We got Uncle Jesse leaving Madeo Tuesday night in Bev Hills -- where our camera guy, of course, asked him about his TV love interest getting busted for allegedly committing bribery and fraud to get her kids into college.

John whipped out a "no comment" real quick, and even though he flashed a peace sign before driving off -- with a sweet doggy bag, BTW -- it's still clear Lori's castmates are concerned.

We got Jodie Tuesday afternoon right after she flew into LAX. She seemed even more upset than John when we asked if she was surprised by the news. Of course she is.

A lot of stunned silence from Lori's pals ... which is kinda how many of her fans feel.
