Sorry for the short diary - Senator Leahy has just issued subpoenas on the floor of the Senate.
Please tune into C-Span 2 for live speech, he is laying it all out for the entire country to hear how the Bush Administration has exceeded the boundaries of law and ignored the Constitution.
It is well past time to restore the Constitution.
Update - (from memory...which is poor) Leahy laid out the reasons for the executive overreach, specifying that he has sought testimony in the USA firings that were unprecedented in scope. He admitted to not taking this step lightly, however the stonewalling of the White House (especially ordering a private citizen NOT to testify!!) had to end.
If someone out there could post a youtube link, I would appreciate it! Meanwhile, here is some linky goodness from The Hill.
