The Dallas convention center - a massive venue usually for concerts and sports - is set to house up to 3,000 migrant teen boys.

But Republican critics blame Biden for relaxing some of Trump's hardline immigration policies for fueling the problem.
Senior Republican lawmaker Kevin McCarthy visited the border on Monday:
"There's no other way to claim it than a Biden border crisis."
The Dallas convention center is one of the country's largest, according to its website, with more than one million square feet of exhibit space and 88 meeting rooms. It is normally used for expos, sports events, concerts and auto shows.
