JEFFERSON CITY, Mo. (AP) – Some Missouri lawmakers want to repeal a law prohibiting the state from complying with a federal proof-of-identity law.

Sen. Ryan Silvey introduced a bill Wednesday to bring Missouri licenses in line with the Department of Homeland Security’s Real ID standards. People who object to the new licenses could get a different ID. A similar bill was filed in the House.

Missouri and four other states don’t comply with the Real ID Act. That means its licenses can’t be used as identification at certain federal facilities, and in two years they won’t be accepted for airline travel. Missouri passed a law in 2009 prohibiting the state from implementing Real ID.

The Department of Revenue says it would need to begin work this year to meet Real ID requirements by 2018.
