As Lori Loughlin and her husband, Mossimo Giannulli, move closer to their trial for their alleged participation in the national college admissions scam, they may run into new hurdles due to the "farcical" nature of their defense.

In 2019, both Loughlin and Giannulli allegedly paid William "Rick" Singer $500,000 so that their daughters, Olivia Jade and Isabella Rose, could attend the University of Southern California (USC). Subsequently, they were each charged with mail and wire fraud, honest services mail and wire fraud, money laundering, and conspiracy to commit federal programs bribery.

Now, a new legal filing has revealed how the prosecution is looking at the couple's defense.

According to the Boston Globe, prosecutors have stated that the "Fuller House" star's assertion that Singer told some of his clients that their donations were legitimate is problematic in their eyes.

"The defendants' contention that, if [admitted scam ringleader William 'Rick'] Singer did in fact tell some clients that their admissions-related donations were legitimate,' that would 'corroborate[] Defendants' lack of fraudulent intent, is farcical," the filing from U.S. Attorney Andrew E. Lelling's office stated.

As noted by the outlet, prosecutors also had "sharp words" for the "When Calls the Heart" actress' camp as they say they had been "misguided in their quest for 302s detailing Singer's statements about what he told other parents who haven't been charged."

"[T]he defendants correctly note that the government has not disclosed the substance of Singer's statements to investigators about what he told other, uncharged parents. That is because those statements are not exculpatory as to these defendants," it stated.

Loughlin's defense has been the subject of much discussion in recent months as reports have continued to surface regarding how she plans to address her upcoming trial. Both Loughlin and Giannulli reportedly believe that they have a "secret weapon" that will prove their innocence, and some have said they also believe that withheld evidence could work in their favor.

However, the prosecution is said to be in possession of an email that could prove Giannulli's guilt. It has been said that Loughlin has tried to "prevent" the prosecution from securing a conviction.

At this time, it also remains unclear whether Olivia Jade and Isabella Rose will appear as defendants.
