(CNN) - After barely a week on the job, Barack Obama's Muslim outreach adviser resigned from the campaign after an old business connection with a fundamentalist Islamic imam surfaced last week.
Mazen Asbahi, a Chicago corporate lawyer, stepped down Monday after joining the campaign on July 26 as its national coordinator for Muslim affairs. The Wall Street Journal first reported the resignation on Tuesday night.
In a letter to the campaign, Asbahi wrote, "I am stepping down from the volunteer role I recently agreed to take on with the Obama campaign as Arab American and Muslim American outreach coordinator in order to avoid distracting from Barack Obama's message of change."
Asbahi served on the board of the Delaware-based Allied Assets Advisors Fund for a brief period in 2000 with Jamal Said, the imam of a fundamentalist mosque outside Chicago, the Wall Street Journal reports. The report links Said to fundamentalist groups Hamas and the Muslim Brotherhood and says he was named by the Justice Department as an unindicted co-conspirator in the racketeering trial of suspected Hamas fundraisers that ended in a mistrial.
"I served on that board for only a few weeks before resigning as soon as I became aware of public allegations against another member of the board," Asbahi wrote in his letter to the campaign.
The fund is a subsidiary of a company that promotes a conservative brand of Islam and Asbahi regularly speaks to groups with ties to the Muslim Brotherhood, the newspaper reported.
"Mr. Asbahi has informed the campaign that he no longer wishes to serve in his volunteer position, and we are in the process of searching for a new national Arab American and Muslim American outreach coordinator," Obama spokesman Ben LaBolt wrote in an e-mail.
Obama has had to balance dispelling rumors that he is a Muslim while trying not to offend Muslims.
"This is a classic example of a no-win situation, right?" Obama responded at a forum for minority journalists on July 27 when asked if he will visit a mosque as a candidate.
"I have repeatedly on various occasions said I am not a Muslim, but this whole strategy of suggesting that I am is indicative of anti-Muslim sentiment that we have to fight against."
