A Republican witness at today’s House Judiciary subcommittee hearing on legislation making English the official language of the United States is from an organization with ties to racism.

Dr. Rosalie Porter, chairwoman of the board of ProEnglish, is testifying in support of the “English Language Unity Act of 2011” before the House Judiciary Committee’s Subcommittee on the Constitution on Thursday morning.

ProEnglish is headed by executive director Robert Vandervoort, who came under fire for hosting a panel at the Conservative Political Action Conference (CPAC) this year featuring Peter Brimelow of the website VDARE, an organization labeled as a white nationalist hate group by the Southern Poverty Law Center. The panel also featured a speech from then-National Review editor John Derbyshire, who would later be fired from the magazine for writing a racist article in the wake of the shooting of Trayvon Martin.

Porter also spoke on the CPAC panel, where the immigrant and former bilingual teacher called bilingual education an “insane idea.”

Rep. Steve King (R), the sponsor of the bill (which has 120 cosponsors), spoke at the CPAC panel as well, where he complained that an unnamed Republican leader would not let him be floor manager of an English-only bill because he wasn’t an immigrant (it’s unclear if that has changed, King’s office did not respond to a request for comment). King will attend a press conference alongside ProEnglish after Thursday’s subcommittee hearing.
