Joe Biden, Tear Down Stephen Miller’s Administrative Wall Rather than shred Trump’s immigration restrictions, Biden is responding with his own regulations that may only make things worse. Chip Somodevilla/Getty Images For all the talk of constructing a wall on America’s southern border over the past five years, one of the Trump-era notions less discussed outside the immigration policy world was that of a wall of paper—a near-insurmountable obstacle largely designed by nativist zealot Stephen Miller, built not out of steel and concrete but federal regulations and policy guides, all intermeshing to trip up would-be immigrants of every category. It may be one of the former president’s most enduring legacies, due not only to the procedural difficulty in bringing it down but to President Joe Biden’s apparent discomfort with aggressively moving to begin its deconstruction. From the immigration courts to the border, the specter of Trump’s regulatory monster still looms large.
