(CNN) Actress Lori Loughlin and her husband, Mossimo Giannulli, have pleaded not guilty to two conspiracy charges in the college admissions scandal, according to federal court filings entered Monday.

They also waived their right to appear in court for an arraignment on a money laundering charge, according to the signed documents.

Loughlin's not guilty plea to charges of conspiracy to commit fraud and conspiracy to commit money laundering is her first substantive response in the case. Prosecutors say she and Giannulli paid $500,000 to a fake charity to get their two daughters accepted into the University of Southern California, falsely designating them as crew recruits.

The "Full House" actress is the highest-profile figure caught up in a scandal that has embroiled dozens of wealthy parents, college coaches and standardized test administrators. Prosecutors say some of the parents facilitated cheating on the SATs and ACTs on behalf of their children, and some parents bribed college coaches to smooth their children's path into college.

Loughlin's decision not to plead guilty in the case has already had significant legal repercussions.
