Texas Governor Greg Abbott defied President Joe Biden‘s new asylum proposal on Friday amid tensions over the U.S.-Mexico border.

Texas has faced the brunt of the massive surge of migrants crossing illegally into the United States through the southern border in recent years. Abbott has used deterrence tactics, such as putting razor wire along the U.S.-Mexico border, and has bused migrants who do come through the border to sanctuary cities.

On Thursday, Biden unveiled proposals aimed at speeding up the asylum claims process for some migrants, including those with prior criminal convictions. For these categories, asylum officers would be given the power to decide migrants are ineligible for asylum at their initial screening, rather than waiting potentially months for a judge to make the ruling.
