The FCC has just sent 13,000 pages of LightSquared documents to Republican leaders of the House Energy & Commerce Committee.

Here’s a few details from Multichannel:

It has been a month since the Feb. 28 request by Reps. Fred Upton (R-Mich.) E&C Committee chair; Greg Walden (R-Ore.), Communications Subcommittee chair; and Cliff Stearns (R.-Fla.), Oversight and Investigations Subcommittee chairman for information pertaining to the FCC’s waiver to LightSquared, which it is now planning to rescind due to GPS interference issues.

The legislators did not give the FCC a deadline, but the release of those documents is expected to trigger their vetting by Sen. Charles Grassley (R-Iowa) — the committee has signaled it will share them — after which Grassley has suggested he may lift the threatened hold on FCC commissioner nominees Jessica Rosenworcel and Ajit Pai.

The FCC would not share the documents with Grassley because he does not chair one of the FCC oversight committees, which prompted the senator to put the hold threat on the nominees.
