On Thursday, a former attorney for Donald Trump entered a guilty plea and promised to testify against the former president in the event that he is called upon for helping to reverse his election setback in the state of Georgia.

Sidney Powell, the attorney, entered a guilty plea to six misdemeanor counts of conspiracy to commit deliberate interference with the performance of election responsibilities. She consented to testify if the prosecution asked her to against Trump and the other sixteen defendants in the case.

The Georgia case is one of four concurrent criminal cases that Trump, the frontrunner for the 2024 Republican presidential nomination, is facing, and one of two specifically focused on his attempts to overturn his election defeat. Trump continues to falsely claim his loss was the result of fraud.

Powell’s plea came just days before she was set to go to trial beginning on Monday on charges including racketeering and conspiracy to commit election fraud.

A lawyer for Powell did not immediately return a request for comment.

Trump has pleaded not guilty to a sweeping Fulton County, Georgia, indictment charging him with violating the state’s Racketeer Influenced and Corrupt Organizations, or RICO, act in his efforts to overturn his loss to Democratic President Joe Biden.

Powell admitted to plotting to unlawfully access secure election machines in rural Coffee County in southeastern Georgia in January 2021. The plea agreement calls for her to be sentenced to six years of probation.
