One of Zarqawi's financiers is Syrian Sulayman Khalid Darwish so designated by the U.S. Treasury Department. Douglas Farah says that Zarqawi may have even given financial aid to Saddam's Ba'athist remnants when Ba'athists money shipments were delayed.
"Darwish was responsible for sending $10,000 to $12,000 to Zarqawi every 20 to 25 days. He also is responsible for recruiting combatants for Iraq, and is an expert in forging documents. Replacing him in the latter operation may be the most difficult and most crucial for the network. While there are numerous replacements for bagmen and recruiters, a good document forger is hard to find."
