Texas Governor Greg Abbott and Tennessee Governor Bill Lee, along with 11 other Republican governors, are joining forces to tackle the escalating border crisis, with over 10,000 migrants arrested in the area in a week. Lee has committed to sending extra troops from the Tennessee National Guard to join Texas' efforts within two months. This comes as Texas is suing the federal government over its attempts to dismantle border barriers, escalating the dispute over border control. The crisis has been described as the most severe border crisis the US has experienced in decades by Lee's office, which added that the situation will only worsen without intervention.
