LINCOLN, Neb. (AP) — Gov. Pete Ricketts says he’s willing to send more Nebraska National Guard troops to the United States-Mexican border to supplement the ones that are already there.

Nebraska has 48 soldiers who were already deployed to work along the border in August and October at President Donald Trump’s request. Ricketts made the comments on Friday as four migrant caravans make their way toward the U.S.

Nebraska has deployed troops to the border over the years to help support the federal government’s security missions. Their deployment wasn’t related to Trump’s recent request to add more troops along the border. They aren’t participating in any federal enforcement operations in the field.

Ricketts says the state is “ready to send additional troops to aid this mission if called upon.”
