Verizon Communications on Monday named Randal S. Milch executive vice president of global public policy and communications, the lead role in Washington for the telecom giant.

Milch in effect replaces Thomas J. Tauke, who is switching gears to advise chief executive Lowell McAdam on legislative strategy including federal telecom law and corporate tax reform, the firm said.

The changes were part of a broader organizational shift with Verizon merging federal, state and legal operations.

Verizon Communications has pushed for legislative reforms of telecom rules and has fought the Federal Communications Commission in federal court. Verizon has argued the FCC does not have authority to regulate broadband Internet providers, including Verizon Wireless. Verizon Communications and Britain’s Vodafone jointly own the wireless carrier with more than 120 million subscribers.

Tauke, 62, served as a Republican representative of Iowa from 1979 to 1991. He led the Verizon’s purchase of spectrum in a 2008 auction, fought against Internet access rules and closed the company’s purchase of wireless spectrum earlier this year from cable firms Comcast, Time Warner and Cox.
