You've been slipped a load of Liberal media koolaid. If you're interested in the facts they are as follows:
Holder NEVER served under Bush. Holder became AG 2/3/09 (Obama). He had previously been Deputy AG under Clinton from 6/13/97-1/20/01. In the time in between he worked for the law firm who specialized in representing GITMO Terrorists.
Under Bush the predecessor of "Fast and Furious" actually 1) tried to track and intercept the guns 2) informed the US and Mexican agents in Mexico for their assistance in that tracking 3) did intercept guns before they were used in crimes and 4) was ended after a few hundred guns were sold because some slipped through those safeguards.
In contrast "Fast and Furious" 1) never even attempted to track ANY of those guns 2) kept US and Mexican agents in Mexico totally in the dark 3) never intercepted a single gun before it was used in a crime and 4) kept going even as hundreds upon hundreds of those guns were recovered in drug murder after drug murder AND WOULD NOT HAVE STOPPED EVEN AFTER BORDER PATROL AGENT TERRY WAS MURDERED IF ATF WHISTLEBLOWERS DID NOT ACT!
Holder briefly served as Acting Attorney General under the George W. Bush Administration — that is a fact.
