Yimmi Fontenot, the press secretary for Republicans on the House Foreign Affairs Committee, which issued the subpoena, told The Epoch Times that the State Department has not sent over the cable.

The committee subpoenaed Blinken in March for the cable, which, as The Wall Street Journal first reported, showed the U.S. Embassy in Kabul warning Foggy Bottom about the Taliban quickly gaining ground and the Afghan forces falling apart. They gave suggestions on how to expedite an evacuation and alleviate the situation.

"The cable, dated July 13, also called for the State Department to use tougher language in describing the atrocities being committed by the Taliban," reported WSJ, citing a person familiar with it. The withdrawal was completed at the end of the following month.

"This committee is empowered by the U.S. Constitution to conduct oversight of the State Department," said committee chairman Rep. Michael McCaul (R-Texas) in announcing the subpoena on March 28.

"We have made multiple good faith attempts to find common ground so we could see this critical piece of information. Unfortunately, Secretary Blinken has refused to provide the Dissent Cable and his response to the cable, forcing me to issue my first subpoena as chairman of this committee."
