The October 1, 2020 deadline for Americans to obtain a Real ID in order to pass through airport security checkpoints has been delayed again, President Donald Trump announced this week.

U.S. military installations are no longer allowing visitors to gain base access using official ID cards from five states -- Illinois, New Mexico, Missouri, Washington and Minnesota -- because those cards don’t comply with federal standards.

Fliers who don't have the latest driver's licenses will have a two-year reprieve before their IDs are rejected at airport security checkpoints.

The Los Alamos National Laboratory may require U.S. passports for entry. 

 Illinois is working on a plan to bring state driver's licenses up to federal security standards. 

Federal authorities say the proposed design for a California driver's license for immigrants in the country illegally doesn't meet national security standards.

Nearly eight years after Congress first passed the REAL ID Act, half of US states are in compliance.
