President Barack Obama wraps up his visit to the Summit of the Americas with a news conference today, his message blurred by scandal and opposition from other Western Hemisphere leaders to the U.S. insistence on the continuing exclusion of Cuba.

A U.S. lawmaker says a "significant number" of Secret Service agents involved in an alleged prostitution scandal at an international summit brought women back to their hotel rooms before President Barack Obama arrived in Colombia.
