Six Republican senators are recommending Brett McGurk's name be withdrawn from consideration for the Iraq ambassador post a week after racy e-mails emerged suggesting he allegedly had an affair with a reporter.
"Recent information has surfaced to call into question the prudence of moving forward with the nominee at this time," said the letter to President Barack Obama signed by six GOP members of the Senate Foreign Relations Committee.
"As members of the Committee, with the responsibility of providing advice and consent, we write to respectfully urge you to reconsider this nomination. There are strong concerns about Mr. McGurk's qualifications, his ability to work with Iraqi officials, and now his judgment."
The letter sent Wednesday was singed by Senators Marco Rubio of Florida, Jim DeMint of South Carolina, John Barrasso of Wyoming, Mike Lee of Utah, James Risch of Idaho and James Inhofe of Oklahoma.
The e-mails were posted online anonymously last week, first on photo-sharing site Flickr and then on the blog Cryptome. The messages are purportedly from 2008 between Brett McGurk, a top adviser on Iraq to then-President George W. Bush, and reporter Gina Chon. The pair later married.
CNN has not independently authenticated the e-mails.
Chon resigned Tuesday, the Wall Street Journal said.
White House press secretary, Jay Carney, said Obama stands by the nominee.
"I would simply say that we believe that the United States will be greatly served by Mr. McGurk's experience in Iraq, which is substantial," Carney said.
Carney said the issue is more about a difference of opinion on war strategy rather than opinions on McGurk.
"There are some who believe we should still be at war in Iraq. There are some who believe the president should not have ended U.S. involvement in the war in Iraq. The president simply disagrees," Carney said.
McGurk was married to another woman in 2006, but it is not clear whether he was still married at the time of his alleged 2008 e-mail exchanges with Chon.
