As part of the LaRouche trials of the late 1980s, starting with LaRouche's own federal trial, conviction, and imprisonment, Molly Kronberg was tried with other LaRouche followers in 1989 in New York and convicted of one count of scheme to defraud. She was sentenced to five years probation; the other LaRouche followers convicted, Robert Primack and Lynne Speed, were sentenced to prison, although Lynne Speed was later able to argue successfully before the state Court of Appeals that the Judge's leniency towards Kronberg should extend to herself as well. According to Avi Klein, Molly Kronberg strenuously opposed having LaRouche testify in the New York trial.
