A pedestrian from State A properly brought a diversity action against a delivery driver from State B and the driver's employer, also a State B citizen, in the federal district court for State B. After being served with the complaint, the employer asserted a crossclaim against the delivery driver. The crossclaim asserts that the accident was the fault of the driver, and that the driver was not operating the truck within the scope of his employment because the driver's license had been suspended a month before. Does the federal court have jurisdiction to allow the company's cross-claim?
