DES MOINES, Iowa (AP) — Iowa Congressman Steve King says he’ll travel to Texas this weekend to learn more about a surge in unaccompanied children from other countries who are entering the U.S. King announced he’ll accompany Minnesota U.S. Rep. Michele Bachmann on Friday on a trip to Texas.

They will visit Brownsville, McAllen and Laredo, where they will meet with border patrol authorities and other officials. They will return Monday. More than 57,000 minors have arrived at the border since October. Most are from Honduras, Guatemala and El Salvador.
