“Did I expect this book party to become a purple moment? No. But when I called some of the people to be co-sponsors and I got [former Pennsylvania Gov. Tom Ridge (R)] and [former Pennsylvania Gov. Ed Rendell (D] I started saying, ‘Geez, maybe this is a good occasion to bring all of my eclectic friends [together].’ ”

The venue actually had to be changed after Davis realized instead of the 50 to 70 people he anticipated, the crowd would be closer to 250.

Davis, who writes a column for The Hill, was particularly surprised to get a call from Issa, whom he says he’s been “very critical” of in his writing and TV appearances. Davis says the congressman expressed interest in “hitting the reset button” and accepted an invite to attend the shindig along with Cummings.

In addition to the two lawmakers, some of the co-sponsors include former Rep. Connie Mack (R-Fla.), Erskine Bowles, George Stephanopoulos, former White House press secretary Mike McCurry and Americans for Tax Reform President Grover Norquist.

Calling it a potentially “kumbaya moment” in the nation’s capital, Davis says, “For goodness sake, Grover Norquist and Mike McCurry aren’t exactly on the same side of the fence!”

Davis laughed when asked if he’s hiring some extra security for the bipartisan affair to celebrate his book on crisis management. “I don’t know if it’s just the co-hosts, I don’t think it’s necessarily me or the book, but I’ve caught on to some kind of wave,” he exclaims.
