1. Does § 301 of the LMRA preempt claims brought in federal court under federal statutes, like the RICO claims in this case?

3. Must, as the panel majority held in this case, statutory claims be arbitrated if a collective bargaining agreement contains arbitration provisions that do not expressly exclude statutory claims from arbitration?
