Chicago and Portland are the latest cities to join a protest limiting travel to North Carolina over a recently approved anti-gay bill.

Chicago Mayor Rahm Emanuel told Crain's Chicago Business that he'll sign an executive order barring city employees from non-essential travel to the state.

“North Carolina's values are of exclusion and intolerance, versus tolerance and inclusion,” Emanuel said.

The second-term mayor added that he plans to recruit companies to relocate to a “more inclusive” Chicago.

“I have already been on the phone and asked my staff to develop a list of companies … that would be interested in [being] in a different environment from one of exclusion,” Emanuel said.

North Carolina's House Bill 2 prohibits any city, town or municipality from enacting measures that prohibit discrimination based on sexual orientation or gender identity and bars students attending public institutions from using the bathroom that does not conform to their gender at birth. It effectively nullified an LGBT protections ordinance set to take effect this week in Charlotte.

The Portland City Council unanimously approved a resolution condemning passage of the bill and barring city employees from non-essential travel to the state.

Several states, including Oregon, Washington and Vermont, have either banned travel or condemned the bill.

Emanuel joins San Francisco Mayor Ed Lee, Seattle Mayor Ed Murray and New York City Mayor Bill De Blasio in implementing such a ban.
