In an off-the-cuff speech that drew both laughs and a few tears from the largely female audience, Heitkamp, 57, described her initial doctor visits prior to her 2000 cancer diagnosis. 

After being told by doctors that she probably had an infection and to start taking antibodies, Heitkamp admitted, “If there’s one thing I’m really bad at, it’s anything that requires a routine.” She then cracked, “This is an excellent place for me, let me tell you, Washington, D.C.”

Rep. Billy Long (R-Mo.) and ABC News’ Cokie Roberts also delivered remarks at the sold-out soiree.
