President Donald Trump has authorized Texas National Guard troops to be sent to Illinois and other states to bolster federal immigration enforcement.
The order has already triggered legal challenges in multiple states.

Pritzker has condemned the federal authorization, calling it an 鈥渋nvasion.鈥 On Monday, Illinois and Chicago to block the deployment, but a federal judge quickly declined to pause the order. A follow-up hearing is scheduled for Thursday.
During , Pritzker Texas Gov. Greg Abbott to 鈥渋mmediately withdraw his support for this decision.鈥 But Abbott says he鈥檚 fully backing the president鈥檚 order.
鈥淵ou can either fully enforce protection for federal employees or get out of the way and let Texas Guard do it,鈥 Abbott .

Who controls the National Guard?
Normally, governors control their state鈥檚 National Guard, often activating troops for emergencies like natural disasters or civil unrest. But under federal law, the president can 鈥渇ederalize鈥 the Guard, transferring command from the governor to the Department of Defense.
The president can only 鈥 like if the U.S. is under attack from a foreign country, or as the Trump administration is arguing in this case, if there鈥檚 a perceived threat of rebellion against the federal government.
Legal experts say the ongoing fight in Illinois could mirror what鈥檚 already happened in Oregon. Geoffrey Corn, chair of criminal law at Texas Tech University, said the dispute largely centers on how the term 鈥渞ebellion鈥 is defined.
"They basically boil down to a rejection of the president's assertion that these activities that he's responding to amount to a rebellion," Corn said. "It's inconsistent with the common sense notion of rebellion."
