PHOENIX — A state lawmaker who wants to reinstate a 1950s federal deportation program known as “Operation Wetback” is under fire again for sending supporters information from a white separatist group.

Rep. Russell Pearce, a Republican, has apologized for sending an e-mail of an article from the West Virginia-based National Alliance. But that hasn’t stopped criticism from all directions, including state GOP leaders.

Arizona Republican Chairman Matt Salmon called the e-mail a “severe mistake,” while Rep. J. D. Hayworth says he no longer supports Mr. Pearce’s reelection bid.

“Given the regrettable and disturbing nature of the e-mail Russell Pearce circulated earlier this week, I cannot in good conscience lend my endorsement to his candidacy for State Representative,” Mr. Hayworth said in a statement.

The article lashes out at how the press portrays “any racially conscious White person who looks askance at miscegenation or at the rapidly darkening racial situation in America.”

It says the “media masters” force on the public their view of “a world in which every voice proclaims the equality of the races, the inerrant nature of the Jewish ‘Holocaust’ tale, the wickedness of attempting to halt the flood of non-White aliens pouring across our borders … .”

Mr. Pearce said he immediately sent two apologies to supporters after forwarding the article. He said he did not know what the group was and that he had not read the entire article before copying it into his e-mail.

“My heart is really hurt to think something like that would go out under my name,” Mr. Pearce said Tuesday. “I was very embarrassed I didn’t have better diligence and read the whole article.”

Governor Napolitano, a Democrat, said Mr. Pearce’s remarks show “an accelerating pattern” of extremism.
