SACRAMENTO, Calif. (AP) — A group of California lawmakers will visit Central America next week to learn about the immigration challenges that are contributing to the U.S. border crisis.

Senate President Pro Tem Darrell Steinberg of Sacramento and several members of the Legislative Latino Caucus will go to El Salvador, Guatemala and Panama on a 10-day political, economic and social mission. The lawmakers, all Democrats, are scheduled to meet the president of El Salvador and other dignitaries.

Steinberg's spokesman, Rhys Williams, says the trip had been planned for months but recent events have made it more relevant. Tens of thousands of unaccompanied children have been arriving at the U.S.-Mexico border from Central American nations.

Williams says some of the costs will be paid by host governments and lawmakers are responsible for their remaining expenses.
