Tucker Carlson's website The Daily Caller reported on Wednesday that a Muslim civil liberties advocacy organization had blocked them from attending a news conference, labeling the conservative outlet a "hate group."

According to The Daily Caller's Vince Coglianese, the Council on American-Islamic Relations (CAIR) had scheduled the event to respond to recent attacks on U.S. embassies in Egypt and Libya.

But after reviewing the reporter's credentials, the CAIR communication director Ibrahim Hooper refused to let them join.

"The Daily Caller is not a news outlet, it is a hate group," Hooper allegedly said. "You cannot come in."

"We have any number of press people. In fact, we often have press people who are highly critical, or ask tough questions. But people who report for propagandist, anti-Muslim hate sites are not journalists," he added, according to the report.

Earlier this year, The Daily Caller published two op-eds by a retired Army major general who had falsely suggested that President Barack Obama might be a Muslim. The outlet also published a column by former Rep. Tom Tancredo (R-CO), who implied that there was a sinister relationship between Gov. Rick Perry (R) and the Muslim community in Texas.

Coglianese argued that the CAIR spokesperson took issue with opinion pieces published by The Daily Caller, not the site's reporting.
