Leslie Johnson will resign from her seat on the Prince George's County Council effective July 31.
A spokeswoman for the U.S. Attorney for Maryland would not describe what kind of hearing it will be, but in May, a plea hearing for Leslie Johnson was cancelled.
She was arrested along with her husband, former County Executive Jack Johnson, in November as part of a federal probe into corruption in county government.
Leslie Johnson is accused of destroying a $100,000 check authorities say was given to her husband by a developer. Prosecutors allege that on the day she and her husband were arrested, she was found with $79,600 in her underwear.
Jack Johnson already pleaded guilty to two federal counts of extortion and evidence and witness tampering.
