Lori Loughlin's claims in her motion to dismiss the college bribery case have been denied by the U.S. Attorney.

Prosecutors released a lengthy response to a motion filed by the 55-year-old actress' lawyers last month, in which they staunchly denied allegations of misconduct and, as part of their filing, included two photos showing the actress's daughters on rowing machines.

As part of the new docs, prosecutors included two photos, allegedly taken by Giannulli, showing both daughters using the rowing machines. Prosecutors allege the photos were used to back up Giannulli's false claims regarding their daughters' rowing experience.

According to Loughlin's motion, and a subsequent memo supporting the dismissal motion, Loughlin's lawyers alleged that prosecutors acted inappropriately in regards to one of their main witnesses -- bribery scam ring-leader Rick Singer -- and that they tried to conceal exculpatory evidence.

In the court documents obtained by ET on Wednesday, the government claims there is no basis for the dismissal request.

“The defendants’ core allegations of misconduct are premised on a straw man: that this case is only about bribery. It is not," the response reads. “The defendants are charged with conspiring to engage in a single, sweeping scheme to gain admission for their children to college by, among other things, lying about their academic and athletic qualifications so that complicit coaches, induced by bribes styled as 'donations' to their programs, could purport to recruit them as elite athletes.”

The response goes on to note, "Just because neither [scam ring leader Rick] Singer nor the defendants actually used the word 'bribe' to describe the purported donations doesn’t mean that they were legitimate."

Both Giannulli and Loughlin have pleaded not guilty to all charges leveled against them, claiming their payments were donations to the school and not bribes.

As for Loughlin and Giannulli's attorneys alleging that prosecutors tried to conceal exculpatory evidence, the prosecutors said this was "simply an error," adding that the government has since disclosed the evidence months ahead of the couple's October trial.
