Washington (CNN) - Arizona Gov. Jan Brewer is rejecting a request from a top Senate Democrat to hold the state's controversial immigration bill for one year to give Congress time to pass comprehensive immigration reform.
In a letter dated Thursday and obtained by CNN, Sen. Charles Schumer, D-New York, made the request to Brewer, a Republican.
Schumer, the Democrats' point man for immigration reform in the Senate, called Arizona's concerns about illegal immigration "legitimate security interests" and said he appreciates that Brewer "felt duty-bound to take action to address the security concerns in your state."
"But I simply do not believe the remedy Arizona has enacted will succeed in resolving the problem it is designed to address," Schumer wrote. He called the law, "wrong-hearted" and "likely unconstitutional." He also asked Brewer to call on Arizona's two GOP senators - John McCain and Jon Kyl - to "immediately begin discussions with me to enact" immigration reform.
On Friday, Brewer's office informed CNN of the governor's response.
"The governor is certainly grateful that Sen. Schumer has focused some attention on Arizona's border security plight," said Paul Senseman, Brewer's Deputy Chief of Staff for Communications. But, Senseman continued, Brewer "is waiting for action on border security."
Attempting to highlight federal inaction on the matter, Senseman referred to a letter sent from border state governors, including Brewer, to Congressional leaders in April 2009. It called for more National Guard personnel to help local law enforcement agencies combat violence, crime and illegal immigration along the U.S.-Mexico border.
"The governor has been waiting over a year," Senseman told CNN in reaction to Schumer's letter.
Critics have said the Arizona law, signed by Brewer last month, will lead to racial profiling. Supporters argue it will crack down on illegal immigration.
As originally passed, the bill would have allowed police to ask anyone for proof of legal U.S. residency, based solely on a police officer's suspicion. Brewer signed a bill to amend the law so that officers could check a person's status only if the person had been detained or arrested for another reason.
Brewer said the changes should ease concerns about racial profiling but opponents say the changes are not sufficient.
