There's a piece on the HotAir.com site, written by Ed Morrissey, that raises more questions about the LightSquared debacle and what led up to it:
Most people probably missed this statement from Senator Charles Grassley (R-IA) last week, announcing that he has put holds on two Barack Obama nominees to the Federal Communications Commission (FCC). With most of the political focus on the Republican presidential race, and whatever focus is left concentrated on budget negotiations in Congress, another Senate hold can't really compete for attention at the moment. However, the hold carries significant importance, as Grassley refuses to release the nominees for confirmation until the FCC comes clean on its correspondence with LightSquared and the White House on a series of strange decisions by the FCC to allow politically- connected donors to attempt to create a 4G network on the cheap - and potentially at the expense of GPS users across the nation.
