Cab drivers at Bush Intercontinental Airport in Houston are up in arms over new regulations that require background checks: Houston taxi drivers protest security rules.

A few hundred drivers, toting handmade signs and chanting demands for “justice,” marched around the reflecting pool at 901 Bagby, before filing inside with plans to vent their concerns in front of City Council.

The group’s chief issue, leaders said, is a recent requirement that drivers picking up passengers at Bush Intercontinental and Hobby airports have new photo identification badges.

“It violates the constitutional rights of the cab drivers in that in enacts a very, very strenuous background check,” said Deric Muhammad of the local Ministry of Justice for the Million More Movement, a group helping represent the drivers. “Many of them are being put out of business and not being allowed to work at the airport system for something they may have done in the past.”
