Very good question... Daniel Ellsberg wrote about a related story that was front page "London's Sunday Times" [1] and various foreign press. But searching Google for 2008-2010 there is zero mainstream American news coverage of that story or the 2009 deposition. Yet they covered her earlier whistleblowing heavily between 2002-2004.

Edit: upon further reading it appears to not be an allegation against the FBI but rather Turkish agents which makes this much less news-worthy:

> Turkish agents started gathering information on her, and they found out that she was bisexual. So a Turkish agent struck up a relationship with her. [ ... ] I don’t know if Congresswoman Schakowsky ever was actually blackmailed or did anything for the Turkish woman. http://www.bradblog.com/?p=7429
