In Arizona, while a controversial immigration bill was gutted by the Supreme Court, a contentious policy still allows local police to stop vehicles and ask for documentation of residency.
So far no Republicans have signed on to the legislation and many conservative policy experts have argued that Congress may be overstepping its bounds in addressing an issue that is as multifaceted as how police patrol their local communities.
Roger Clegg, president of the Center for Equal Opportunity, has said in the past he was skeptical about attempts to legislate appropriate behavior under these circumstances, and cautioned against a "one-size-fits-all" approach.
And while opposed to racial profiling, on Tuesday he told U.S. News using the Trayvon Martin case to push for the legislation is a political mistake.
"I think that it is being pushed now is political posturing," Clegg says. " I think that whatever one thinks of what happened in the Trayvon Martin and George Zimmerman case this bill does not address it because law enforcement agents were not involved in the racial profiling if there was any racial profiling."
