Congressman Issa slides excerpts from court-sealed wiretap aplications into the Congressional record as part of the Fast and Furious maneuvering.
Roll Call has excerpts and explains why it is legal:
The wiretap applications are under court seal, and releasing such information to the public would ordinarily be illegal. But Issa appears to be protected by the Speech or Debate Clause in the Constitution, which offers immunity for Congressional speech, especially on a chamber’s floor.
For those for whom excerpts just won't suffice, the June 28 Congressional Record is here (448 page .pdf). The May 24 letter from Issa to Cummings (whoich contains the excerpts) starts in the middle column of page 251/448.
