NeitherOlivia Jadeand Isabella Rose are listed on the USC women’s rowing roster.

The couple pleaded not guilty in April. They had previouslyturned down a plea dealbecause it included jail time.

And while the developments are “not great” for the couple’s marriage, according to the source, Loughlin and Giannulli are “trying to get through the legal hurdle as a team.”

Earlier in May, an insider previouslytold PEOPLEthat “they are both mounting a vigorous defense against the charges.”

“Lori in particular has become extremely well-versed in the case,” the insider said. “She’s an active participant in her own defense, feels like she’s got a valid defense, and that when all the evidence comes out, she won’t be found guilty.”

Reps for Loughlin and Giannulli have not returned PEOPLE’s requests for comment. A trial date has not yet been set.
