From NewsMax:

Democrats howling for the resignation of Secretary of Defense Donald Rumsfeld for not informing them of reports of prisoner abuse in Baghdad are ignoring the fact that concerned parents of an accused soldier informed 16 members of Congress - top Democrats such as Senators Hillary Clinton, Edward Kennedy and John D. Rockefeller - and the governor of West Virginia of the burgeoing scandal as far back as February 26th of this year.
None of these 17 people acted to disclose the detailed information contained in the letters...

Here are the the 17 names, all Democrats except for Rep. Roscoe Bartlett, Sgt. Frederick's congressman:

Senators Jack Reed, Mark Dayton, Robert Byrd, Bill Nelson, Evan Bayh, Mark Pryor, Edward Kennedy, Benjamin Nelson, Hillary Clinton, Joseph Lieberman, Daniel Akaka, Paul Sarbanes, John D. Rockefeller, Governor Mark Warner and Rep. Roscoe Bartlett.

Senator Byrd's office would not even accept the letter e-mailed to him on the grounds it was too long.
