Mike also represents holders in unclaimed property multistate audits, voluntary disclosures, and in litigation.

Chambers recognized Mike as "renowned for his expertise in False Claims Act work" in Illinois, curtailing dozens of Illinois qui tam cases against wine shippers, and testifying against further such actions before an Illinois legislative committee.
