The White House is refusing to allow Politico on Air Force One on Monday, which means the news organization cannot fulfill its press corps pool responsibilities.

Axar.az reports, citing CNN, that a Politico spokesperson confirmed that the publication was excluded from the out-of-town travel pool, a small group of reporters who travel with the president on trips.

The White House tried to enlist other news outlets to take Politico’s place on the trip, but “it was unable to find a replacement,” so “there is no primary print pooler on this trip,” Washington Post reporter Katherine Doyle said in an email to colleagues.

The Post is on the trip in the “secondary” print seat as part of the pool. The “secondary” reporter does not typically send out updates to the wider press corps. But with Trump traveling to Nebraska for a campaign stop on Monday afternoon, The Post is sending out updates while emphasizing that it is not taking Politico’s place.

It should be noted that on September 18, Trump had barred journalists from CNN, MS NOW and Politico from working at the White House. A court later ordered the ban to be lifted.
