Pentagon sending 5,200 troops to border week before midterms

WASHINGTON (AP) — A week out from the midterm elections, the Pentagon said today it is sending 5,200 troops, some armed, to the Southwest border this week in an extraordinary military operation to stop Central American migrants traveling north in two caravans that were still hundreds of miles from the U.S.

The number of troops is more than double the 2,000 who are in Syria fighting the Islamic State group.

President Donald Trump, eager to focus voters on immigration in the lead-up to the elections next week, stepped up his warnings about the caravans, tweeting: "This is an invasion of our Country and our Military is waiting for you!"

His warning came as the Pentagon began executing "Operation Faithful Patriot," described by the commander of U.S. Northern Command as an effort to help Customs and Border Protection stiffen defenses at and near legal entry points. Advanced helicopters will allow border protection agents to swoop down on migrants trying to cross illegally, he said.

"We're going to secure the border," Air Force Gen. Terrence O'Shaughnessy, the Northern Command leader, said at a news conference. He spoke alongside Kevin McAleenan, commissioner of Customs and Border Protection.

Eight hundred troops already are on their way to southern Texas, O'Shaughnessy said, and their numbers will top 5,200 by week's end. He said troops would focus first on Texas, followed by Arizona and then California.

The number of people in the first caravan has dwindled to 3,500 from about 7,000, though a second one was gaining steam and marred by violence. About 600 migrants in the second group tried to cross a bridge from Guatemala to Mexico en masse today but were met by ranks of Mexican federal police who blocked them from entering. The riverbank standoff followed a more violent confrontation Sunday when the migrants used sticks and rocks against Mexico police. One migrant was killed Sunday night by a head wound, but the cause was unclear.
