Lawmakers this week raised fresh questions about the proposed network by Virginia-based Lightsquared, a firm backed by billionaire Philip Falcone, a prominent donor to Obama's Democratic party.

Republican staff members of the committee alleged the Air Force general told lawmakers that Obama administration officials lobbied him to express support in his testimony for the Lightsquare proposal, the Washington Post reported Friday.

At Thursday's hearing, Shelton said the proposed wireless broadband network by Lightsquared would interfere with the Global Positioning System (GPS) relied on by the military and private industry.
