From Hot Air:

It is with great shock and sadness that we offer our condolences and prayers to the family of Jake Brewer, the husband of Mary Katharine Ham, and the father of Georgia and a child on the way, as well as his colleagues and friends at the White House and Change.org. Jake died as a result of an accident while participating in the Ride to Conquer Cancer bicycle rally and fundraiser. He gave his life while trying to help others, a quality that Jake’s friends say is defining about him. Jake passed away yesterday at 34 years of age.

Our prayers are with Mary Katharine and her family. Here is an educational fund that has been set up for her children. I will be contributing and urge you to as well.
