More on possible congressional resistance to domestic spying: Six Ways Congress May Reform NSA Snooping

2) Require NSA analysts to obtain court approval before searching metadata.
3) Declassify Foreign Intelligence Surveillance Court opinions.
4) Change the way Foreign Intelligence Surveillance Court judges are appointed.
5) Appoint a public advocate to argue before the Foreign Intelligence Surveillance Court.
