Airport security changed dramatically after 9/11.
President Trump's executive order on Friday instructed the Department of Homeland Security to pay TSA officers immediately, although it's unclear when the impact of that move will start to be felt at airports.
With spring break in full swing, airline passengers continued to wait it out at major U.S. airports after President Trump signed an executive order to pay TSA officers aimed at alleviating long security lines.
TSA may have to shut down operations at some airports as travelers are experiencing record waiting times, the agency's acting head said, as the latest offer to end a funding impasse and put restraints on Trump's deportation agenda met fierce resistance in Congress.
Travelers going through O'Hare on Monday were divided over the government's decision to send ICE agents to at least 14 airports.
Multiple sources tell ABC News ICE agents will be deployed to 14 airports across the country, but that number could change as plans continue to unfold. It's still not known if Chicago airports are included.
