Delcy Rodriguez seems alive and well, and not enthused with collaboration with the US.

I wouldn't trust Rubio until any evidence comes out of Venezuela. There's no official confirmation of her being sworn in as president (official outlets still refer to her as vice president, which is how it legally works) and she's still a proponent of Chavismo. At any rate, even if she turns coat there'll at least be a power struggle with PSUV, specially with the MoD announcing full scale mobilisations.

Edit:

As I wrote that, there was an update

Vicepresidenta de Venezuela: «aquí hay un solo presidente, y se llama Nicolás Maduro»

Trump can claim whatever he likes, he is not the arbitor of truth.

So, did they really managed their coup? Like the whole hope is lost, and all the build up was for nothing? (Like all the equipment that were bought, all the people, etc).

Im having a mental breakdown over this circus of the world and i wanna hear someone killing imperialism along with its soldiers
