The White House is stripping the White House Correspondents’ Association of its role in managing the White House Press Pool, taking control of deciding who will be a part of the small rotating group of journalists and photographers who accompany the president.

The White House said on Tuesday it would decide which media organizations participate in the press pool that covers the president, wresting control away from the group of journalists that has done so for decades.

Journalists and media critics warned that White House control of the press pool threatens the foundations of a free press.
