John Mica, R-Fla., announced on Wednesday the Transportation and Infrastructure committee would conduct a hearing to review cruise ship safety in light of the accident.
"With cruising no longer simply a vacation for the rich and famous, and millions of American passengers and growing on these megaships, this is a wake-up call to look at safety and make certain we learn from this tragedy," Mica, the committee chairman, told ABC News.
Mica asked Rep. Frank LoBiondo, R-N.J., chairman of the Coast Guard and Maritime Transportation Subcommittee, to help lead the review and preliminary investigations in preparation for a hearing that's planned for February.
Smith and Lau said they would be interested in speaking with U.S. lawmakers about their experience.
"The better way is through the court system," Smith said. "We don't know how we will participate yet, but we plan to participate."
