Two speakers at the Conservative Political Action Conference this week likened Attorney General Eric Holder to segregationist Alabama Gov. George Wallace.

As it turns out, that comparison is actually quite a personal one for Holder.

Both Louisiana Gov. Bobby Jindal (R) and Christian conservative leader Ralph Reed suggested Holder's opposition to school vouchers was tantamount to Wallace's 1963 "Stand in the Schoolhouse Door" to prevent two black students from attending the University of Alabama.

One of the students Wallace attempted to block that day was, in fact, Holder's late sister-in-law, Vivian Malone Jones.

The Justice Department on Friday, in response to Jindal's comment, sent him a copy of Rep. John Lewis's (D-Ga.) book, in which the civil rights leader describes Malone Jones's trials that day.

"This should help the governor brush up on his history for the next time he invokes the civil rights movement," Justice Department spokesman Kevin Lewis said in a statement.

Update 6:43 p.m.: Jindal responds to the DOJ:
