Professional scandal mopper-upper Lanny J. Davis is throwing a big party at The Hamilton on Tuesday night in anticipation of his new book, “Crisis Tales: Five Rules for Coping With Crises in Business, Politics, and Life.”

We were told to get there early because it is going to be packed with Davis’ friends, associates and former clients. Expected guests include the crème de la crème of political Washington, including former Clinton White House Communications Director Mike McCurry, Americans for Tax Reform President Grover Norquist, former Pennsylvania Govs. Edward G. Rendell and Tom Ridge, former head of the Republican National Committee Michael Steele, Supreme Court litigator Ted Olson and ABC “This Week” host George Stephanopoulos and many others, including a powerful woman or two.

The event to toast Davis’ new book, which outlines his techniques on how to weather a scandal, has proved so popular that he actually had to move his party to a larger venue to accommodate all the A-list RSVPs.

Davis will also take his party train north. On Wednesday, he will hold an event at the Philadelphia offices of Dilworth Paxson LLP, and on Monday he’ll hold another at the New York office of Boies, Schiller & Flexner LLP.

We hear he might take a quick trip to the left coast to fete the book, but details on that event are still vague.
