Developing: TVNewser has learned all the networks were prepared to ban the use of pictures and video from Gov. Sarah Palin‘s meetings at the UN today. The ban was in protest of the McCain campaign’s restriction on editorial presence.

We hear the networks had arranged for a pool camera to cover all the meetings, and at least three journalists were to be present as well (one print, one radio, one TV). Earlier today, the McCain campaign said it would allow just one editorial person inside. Later, the campaign limited it to a camera only.

Within the last few minutes, the campaign reversed course and will allow a CNN producer in to the meetings.

Gov. Palin is to meet today with Colombian President Alvaro Uribe and Afghan President Hamid Karzai.

> Update: Kate Snow reports on ABCNews.com about the back-and-forth, and how a CNN producer was eventually allowed access (CNN was pre-designated for pool duty).

> Update, update: Politico has the first pool report from CNN’s Peter Hamby. Total amount of access allowed? “Grand total of 29 seconds,” he writes.
