A Red Carpet for Radicals at the White House

A year-long investigation by the Investigative Project on Terrorism (IPT) has found that scores of known radical Islamists made hundreds of visits to the Obama White House, meeting with top administration officials.

Court documents and other records have identified many of these visitors as belonging to groups serving as fronts for the Muslim Brotherhood, Hamas and other Islamic militant organizations.

The IPT made the discovery combing through millions of White House visitor log entries. IPT compared the visitors’ names with lists of known radical Islamists. Among the visitors were officials representing groups which have:

Been designated by the Department of Justice as unindicted co-conspirators in terrorist trials; Extolled Islamic terrorist groups including Hamas and Hizballah;
Obstructed terrorist investigations by instructing their followers not to cooperate with law enforcement;

Promoted the incendiary conspiratorial allegation that the United States is engaged in a “war against Islam”— a leading tool in recruiting Muslims to carry out acts of terror;
Repeatedly claimed that many of the Islamic terrorists convicted since 9-11 were framed by the U.S government as part of an anti-Muslim profiling campaign.

Individuals from the Council on American-Islamic Relations (CAIR) visited the White House at least 20 times starting in 2009. In 2008, CAIR was listed as an unindicted co-conspirator in the largest terrorist money laundering case in U.S. history – the trial of the Holy Land Foundation in which five HLF officials were convicted of funneling money to Hamas.
