"If Joe Biden federalizes our National Guard, that would be the biggest political mistake you can make, and that's why I think he won't do it," Abbott told Fox News.

The Texas National Guard, deployed by Republican Gov. Greg Abbott, took control of Shelby Park in Eagle Pass on the border with Mexico. Before that, federal border agents used it to hold migrants before transporting them for processing.

The governor of Texas then announced that the US administration had failed to fulfill its responsibilities to protect the border, which led to the state's decision to declare an "invasion and the right of self-defense."

According to the White House, the state governor's actions to protect the American border are dangerous.
