Yes. I believe it is entirely possible that this guy is innocent of taking bribe-oil from Saddam-- which just makes his servitude to Saddam all the more jaw-dropping.
If a Senator in the US were this closely allied to Saddam, it would be nothing short of scandalous-- and said Seantor would certainly not survive re-election.
Maybe you are mistaking his friendship to the Arab world to Saddam. He has always called Saddam a brutal dictator.
