John Dingell was diagnosed with prostate cancer last year. He tweeted this message just a day before his death.
The Lovely Deborah is insisting I rest and stay off here, but after long negotiations we've worked out a deal where she'll keep up with Twitter for me as I dictate the messages. I want to thank you all for your incredibly kind words and prayers. You're not done with me just yet.
