Robert Durnan, Gerald Christian and Mark Forbes also allege in a federal lawsuit filed Monday that they were subjected to retaliatory reassignments or duty restrictions last year after their attorney sought payment for overtime accrued since November 2010. Payroll records show no overtime payments to the men in that period.
The lawsuit claims the men's duties, primarily returning fugitives to Delaware, were taken over by other employees who lacked the proper training, including Biden's former chauffeur.
A spokesman for Biden said officials had not been served the lawsuit, and that the office does not comment on pending litigation.
