"Biden Pledges Border Closure if Congress Approves Bill Amid Overwhelm"

President Biden has pledged to close the U.S.-Mexico border if Congress passes a bipartisan border security deal, granting him emergency authority to do so. The deal would require the border to be shut down if around 5,000 migrants cross illegally in a day, but it faces uncertainty in the GOP-controlled House. Former President Trump is pressuring Republicans to oppose the negotiations, while House Speaker Mike Johnson urges Biden to take executive action to address the border situation. Additionally, tensions between the White House and Texas persist over federal agents' access to Shelby Park.
