The Trump White House press office is refusing to respond to emailed questions from reporters who display their pronouns in their email signatures, saying they deny “biological reality” and can’t be trusted to write honest stories.

New York Times reporter Michael Grynbaum said the press office has rejected emails on “three recent occasions” from reporters who display the gender-identifying label, and attributed quotes to press secretary Karoline Leavitt expressing it as policy.

“As a matter of policy, we do not respond to reporters with pronouns in their bios,” Leavitt told a Times reporter with pronouns in their signature, who had inquired about a climate research observatory.
