Colorado Republican lawmakers say they want to introduce legislation similar to Arizona’s strict immigration law and they’re getting pointers from legislators in Phoenix.

Colorado is the latest state to send a delegation of lawmakers to Arizona to talk about adopting a law similar to the one being challenged by the federal government.

Eleven members of Colorado’s Republican Study Committee are meeting with Arizona legislators this week to get advice on the immigration law and how they’re defending it in court. A federal judge blocked most of the controversial aspects of Arizona’s law a day before it was going to take effect.

Tennessee and Utah are among the other states who sent delegations to Arizona.
