Herb Kohl, Wisconsin Democrat of the Senate Judiciary Committee is asking the top four US wireless carrier’s to justify the “sharply rising rates” they charge for sending and receiving texts form mobile phones.

Kohl, has sent letters to the top exec’s of AT&T Inc, Sprint Nextel Corps, Verizon Wireless, and T-Mobile saying he is concerned with the rising text messaging rates and that they reflect decreasing competition within the wireless business.

Kohl chairs the Judiciary Subcommittee on Antitrust, Competition Policy and Consumer Rights and his enquiry comes as the European Commission is threatening to cap roaming rates for texting.
