Former Pennsylvania Gov. Edward G. Rendell, now a partner with Ballard Spahr, has been hired as a lobbyist for LightSquared, a wireless telecom investment. The company said it hired Gov. Rendell because he has been a strong advocate for increasing investment in American infrastructure. Ballard Spahr partner Adrian King, who served as Gov. Rendell's Deputy Chief of Staff, also is registered as a LightSquared lobbyist.
