WASHINGTON — George Paz, Express Scripts chairman and CEO, and David Snow, Medco Health Solutions chairman and CEO, were in a pair of hot seats Tuesday afternoon before the Senate Committee on the Judiciary Subcommittee on Antitrust, Competition Policy and Consumer Rights. Many of the questions posed by Senators on the subcommittee challenged the respective chief executives on how the proposed merger would negatively impact retail pharmacy and how the proposed merger would result in a dominant marketshare of the mail order pharmacy business.
