Supreme Court Justice Clarence Thomas said that Stanford Law School and some other elite academic institutions are effectively “off limits” to him and other conservatives. Speaking with Peter Robinson at the Hoover Institution, he portrayed this as evidence of ideological exclusion within higher education, despite his position on the country’s highest court.

The article reports that Thomas has never visited Stanford Law School and said such visits would be considered out of bounds in the current political climate. His remarks come amid wider disputes in the United States over free speech, political diversity and the treatment of conservative voices on university campuses.
