I'm sure she did it just so she could have more hateful, speculative, and accusatory stories circulating about her while she recovers. What could be more convenient? She has never refused or even hesitated about testifying. She has been an excellent Secretary of State and there is no reason to believe she won't testify truthfully when she is well. Having a blood clot is a serious condition and she does need time to recover. Ask a friend or loved one who has survived a stroke or heart attack of they don't think so.
