Civil rights advocates on Wednesday are urging constituents to tell their senators to oppose the nomination of Thomas Farr, President Donald Trump’s pick for a federal judgeship in North Carolina.

If confirmed, Farr would fill a more than decade-long vacancy at the U.S. District Court of the Eastern District of North Carolina—a lifetime position that rights groups and Democratic lawmakers say would allow him to further a campaign of suppressing the votes of communities of color and attacking worker rights.

As McClatchy reported last week:

McConnell’s advancement of the nomination drew outrage from a number of advocacy groups including The Leadership Conference on Civil and Human Rights. Vanita Gupta, president and CEO of the organization, denounced “Farr’s unrelenting pursuit of restricting voting rights and defending employment discrimination.”  She added, “At a moment when our courts are under attack, it is more important than ever that those who serve on the bench are fair and independent.”

Rev. William Barber wrote last year that “African-Americans seeking to have their rights protected under federal law have much to fear if Farr takes the bench,” while legal expert Andrew Cohen previously expressed concern over his background, writing that Farr “has yet to fully answer for a professional career rooted in white supremacy and voter suppression.”
