Sen. Amy Klobuchar, D-Minn., plans a hearing on the “kill switch” technology and broader questions of cellphone security, she told us Thursday. The hearing will be later this month within the Senate Judiciary Committee, where she chairs the Antitrust Subcommittee. On Dec. 30, Klobuchar demanded answers from several carriers about their cellphone security efforts and the kill switch, asking on behalf of her subcommittee. No hearing has formally been announced.
