"As surely as if they were placing a hand over a journalist's camera lens, officials in this administration are blocking the public from having an independent view of important functions of the executive branch of government," the letter states, adding that the restrictions imposed by the Obama White House represent a major break from the practices of past administrations.
The news organizations said the White House limits on access raise constitutional concerns about infringement on First Amendment press freedoms and have "a direct and adverse impact on the public's ability to independently monitor and see what its government is doing."
The press coalition, which included The Associated Press, major broadcast and cable networks, wire services, online services and newspapers, said the access limits also undercut Obama's pledge to create a more transparent government, and impose "an arbitrary restraint and unwarranted interference on legitimate newsgathering activities."
The groups requested an immediate meeting with Carney on how to restore full press access.
Simultaneously, the presidents of the American Society of News Editors and the Associated Press Media Editors sent a letter to their members urging them to stop using handout photos and video from the White House.
"We must accept that we, the press, have been enablers," the ASNE-APME letter states. "We urge those of you in news organizations to immediately refrain from publishing any of the photographs or videos released by the White House, just as you would refuse to run verbatim a press release from them."
The AP has a policy against using handout photos from the White House unless they are of significant news value and shot in areas that the press doesn't expect to have access to, such as the Situation Room or the private residence areas of the White House.
Among recent presidential events for which the White House distributed its own photos but denied access to photojournalists:
—An Oct. 11 meeting with Pakistani human rights activist Malala Yousafzai.
—An Aug. 26 meeting with African-American faith leaders.
—A July 30 meeting with Israeli and Palestinian negotiators and Vice President Joe Biden.
—A July 29 meeting with former Secretary of State Hillary Clinton.
"While certain of these events may appear 'private' in nature, the decision of the White House to release its own contemporaneous photograph(s) suggests that the White House believes these events are, in fact, newsworthy and not private," the coalition letter states.
Kathleen Carroll, AP executive editor and senior vice president, said too many public events "are now recorded only by photographers who work directly for the White House, resulting in images that are little more than visual press releases."
"We aren't asking to make pictures of the president putting on his socks in the private quarters every morning," Carroll said. "We are asking simply to be allowed back into the room when he signs legislation, shakes hands with other leaders, and otherwise discharges his public duties."
Santiago Lyon, AP's director of photography, said in a recent speech about press access that when White House photos replace — rather than supplement — independent photos, the result is "images that put the president in a consistently rosy light."
