The debate was held at Drexel University and was televised by NBC News. All candidates except former Alaskan Senator Mike Gravel attended the debate. It was announced on October 19 that Senator Gravel did not meet the polling requirements for the debate, though the DNC did not specifically say what the requirements were; Gravel has suggested that GE, which owns NBC and is a "war-profiteer," conspired to exclude him from the event after, during the previous debate, he questioned Hillary Clinton's signing a resolution that would possibly facilitate entering war with Iran. Instead of attending the debate, Senator Gravel staged an event at the nearby World Cafe Live.
