Apparently this woman contacted her Representative awhile back via letter. The Representative forwarded it to Feinstein, who has
had it since July and did nothing with it due to the woman not wanting her name public. Other Democrats on the committee felt she was holding back information from them through and after the hearings, asked for it, and she gave it to the FBI. Democrats on the committee wanted information from her on what it was and she finally briefed them.
That committee needs younger leadership from each party. Grassley and Feinstein are old and slow and both remind me of Grandfather Clock on Captain Kangaroo.
