Update (2004ET):

Fox News' Bill Melugin reported that Border Patrol agents who were "surrounded" by protesters following a vehicle-ramming attack in the Chicago metro area yesterday had requested local police assistance, which was reportedly rejected by the top brass of the local police force. It remains unclear whether the rejection was due to a shortage of officers or a genuine refusal, given the hostility that the sanctuary city, controlled by radical leftists, has shown toward the Trump administration.

"Prigg v. Pennsylvania said states could decline to help federal law enforcement — not obstruct it. Today's sanctuary jurisdictions have turned "non-cooperation" into active interference, allowing street militias to block ICE. It's no longer federalism, It's nullification," Fox News' Will Ricciardella wrote on X. 

The National Fraternal Order of Police condemned the top leadership of the Chicago Police for prohibiting officers from assisting Border Patrol agents in an urgent time of need. 

"Details are still emerging, but it appears that officers from the Chicago Police Department were ordered not to assist a group of ICE agents while they were physically threatened by what appeared to be an angry mob," Patrick Yoes, National President of the Fraternal Order of Police, wrote in a statement, adding, "Let me be clear, both the National FOP and the Illinois FOP believe that when an officer calls for assistance, you answer, no matter what."

A federal judge has temporarily blocked the Trump administration from deploying roughly 200 Oregon National Guard troops to Portland, halting plans to protect federal assets and personnel amid Antifa-linked attacks on an ICE facility in the southern part of the metro area. Meanwhile, the White House is preparing to send up to 300 Guard troops to crime-ridden Chicago to combat left-wing agitators and assist federal efforts to deport criminal illegal aliens amid attacks over the weekend.

U.S. District Judge Karin Immergut stated on Saturday that there was "no evidence" that protests in the city amounted to a rebellion or significantly hindered law enforcement, and that the White House's justification was "untethered to the facts," according to Reuters. The injunction will remain in place until at least October 18, pending further litigation.
