John McCain, senior member of the Senate Commerce Committee, has special mobile phone cell coverage at Cindy McCain’s 15-acre ranch.

By the time Sen. John McCain’s presidential bid was in full swing this summer, the ranch had wireless coverage from the two cellular companies most often used by campaign staff—Verizon Wireless and AT&T.

Verizon delivered a portable tower know as a “cell site on wheels”—free of charge—to Cindy McCain’s property in June in response to an online request from Cindy McCain’s staff early last year. Such devices are usually reserved for restoring service when cell coverage is knocked out during emergencies, such as hurricanes.
