I've checked hundreds of sources on Eric Holder and none of them support what you're saying . See google "Eric Holder biography." He working for "Covington & Burling" law firm during the entire Bush Presidency.
Holder remained in his postion for approximately 2 weeks after Bush was sworn in, simply because the Dems threw a hissy fit and made Ashcroft’s confirmation quite an ordeal.

Or, you may ask congresswoman from Texas, Sheilah Jackson-Lee.
