Politico has the statements:
“I've known her for most of her adult life and I know she's straight,” said Sarah Walzer, Kagan's roommate in law school and a close friend since then. “She dated men when we were in law school, we talked about men — who in our class was cute, who she would like to date, all of those things. She definitely dated when she was in D.C. after law school, when she was in Chicago – and she just didn't find the right person.”
Walzer, half amused and half appalled to be discussing her friend's sexual orientation, agreed to be interviewed after Kagan's supporters decided they should tactfully put an end to the rumor, which White House officials had already tried to squelch in background interviews with reporters. She said she decided to talk to POLITICO because the discussion of Kagan's personal life has become a “distraction.”
“It's taking away from substantive discussion of the issues from a really substantive person who deserves to be given the opportunity to address the substantive issues,” she said.
