As the Summit of the Americas gets under way today, there is one embarrassing incident which threatens to distract from international efforts to focus on trade and the economy. Twelve U.S. Secret Service agents have already been sent home for alleged misconduct involving prostitutes in Cartagena. The agents have been replaced and the Secret Service says its security plans at the summit has not been compromised.
This week, Mitt Romney and Rick Santorum got their secret service code names. Mr. Romney is Javelin. Mr. Santorum is Petrus. We asked Ian Chillag and Mike Danforth from the NPR podcast How to Do Everything to look into how secret service code names are assigned.

MIKE DANFORTH, BYLINE: Here's historian Michael Beschloss.
