Too bad these are not set-up for use in oral arguments--maybe next year:
1) Is Jeff Sessions allegedly false committee testimony about speaking with the Russian ambassador protected from prosecution by Speech or Debate (the post links to other discussions, which link to more discussion). "Legislative functions" go beyond speaking. But is all speech in the chamber necessarily legislative?
2) The Second Circuit heard arguments over whether the Religious Freedom Restoration Act allows for damages against federal officers, either through Bivens or through a private right of action in the statute.
