Border Patrol officials say they are planning for as many as 18,000 arrivals daily once the health policy, known as the Title 42 authority, expires in May. Last week, about 7,100 migrants were coming a day to the southern U.S. border.

Former Trump administration officials are pressing Texas Gov. Greg Abbott to declare an “invasion” along the U.S.-Mexico border and give thousands of state troopers and National Guard members sweeping new authority to turn back migrants, essentially bestowing enforcement powers that have been a federal responsibility, AP reports.

The concept is legally dubious, nearly unprecedented and would almost certainly face swift court challenges, according to some constitutional experts.

The urging comes as the Republican governor prepares to announce Wednesday “unprecedented actions” to deter migrants coming to Texas. The move came in response to the Biden administration announcing last week it will end the use of a public health law that has limited asylum in the name of preventing the spread of COVID-19.
