Yes he was and I beleive the Bush White House was going to refuse him access to a meeting there, then it was found out that he was one of Bonior's staffers and was allowed through.
I could see Baghdad Bonior screeching to his NYT and WashCompost comrades, "racial profiling" if he was refused access to the meeting.
The son was allowed in, then removed and not allowed to stay for the meeting. This was just a few weeks after the father's visit.
Indeed a stink was raised and the WH issued an apology and Bush wrote the son a note, to tamp down the spurious charges of racism.
As far as has been documented, THAT was the last contact the Bush Administration had with Al-Arian politically.
We all know the elder was just arrested.
