A group of congressional Democrats is urging the State Department to restart chartered evacuation flights and take additional steps to help U.S. citizens who wish to leave Israel amid the ongoing war with Iran.

The lawmakers described the State Department’s current partnership with El Al, which launched on March 13 with a limited number of special evacuation flights for U.S. citizens, as insufficient. The Israeli airline has currently suspended registration for the flights, and government-imposed security restrictions are limiting passenger capacity on each flight and reducing airport operations.

“We were shocked to learn this week that as the military conflict in Iran escalates and continues to threaten the safety of U.S. citizens in the Middle East, the State Department has abruptly and effectively ended emergency evacuations for Americans out of Israel,” the lawmakers said in a letter to Secretary of State Marco Rubio on Thursday. “As Israel continues to face threats from hostilities with Iran, the State Department cannot abandon American citizens abroad. Failing to assist Americans in their time of need is totally unacceptable.”

The letter, led by Rep. Laura Gillen (D-NY), was co-signed by Senate Minority Leader Chuck Schumer (D-NY) and Reps. Yvette Clarke (D-NY), Don Davis (D-NC), Dan Goldman (D-NY), Josh Gottheimer (D-NJ), Julie Johnson (D-TX), Greg Landsman (D-OH), George Latimer (D-NY), Jared Moskowitz (D-FL), Jerry Nadler (D-NY), Pat Ryan (D-NY), Tom Suozzi (D-NY), Ritchie Torres (D-NY), John Mannion (D-NY), Haley Stevens (D-MI), Joe Morelle (D-NY) and Johnny Olszewski (D-MD).

According to the letter, the State Department is urging Americans to rely on commercial transportation or the Israeli Ministry of Tourism, and El Al lacks the capacity to carry all U.S. citizens who wish to depart, leaving Americans “without real options.” The information provided by the State Department, the letter reads, is “causing frustration, anxiety, and fear.”

“In the midst of a conflict, U.S. citizens should not have to wait weeks to be able to board a commercial flight or cross the Israeli border into another country to find their way home. It is unacceptable for the State Department to leave them on their own,” the letter continues.

In a press release Thursday, the State Department heralded its partnership with El Al, which it said has “already allowed more than 2,000 American citizens to return to the United States from Israel.” 

The airline “will continue to reserve a percentage of seats on all regular U.S.-bound flights for Americans wishing to depart Israel” and has 28 flights scheduled over the next week “to the extent permitted by the Israeli authorities,” the State Department said. The release did not acknowledge that the registration form for the evacuation flights is currently closed.

Democrats have accused the administration of failing to adequately prepare to evacuate U.S. civilians, or government personnel, from the Middle East before launching the war in Iran.

The lawmakers called on the State Department to restart charter flights from Israel and elsewhere in the region; reopen the State Department’s crisis intake form, which helps citizens receive emergency information; activate a crisis task force to assist Americans attempting to leave Israel; and provide clearer information on commercial air travel options.

Thousands of Americans, currently in Israel, are unable to access flights home and are not being offered alternative travel options or any additional assistance by the State Department,” their letter reads. “Additionally, the Department’s inconsistent guidance and lack of responsiveness have added to uncertainty and fear, making the situation even more dire for impacted families.”

In its press release, the State Department defended its evacuation efforts: “After the launch of Operation Epic Fury, the Department offered charter flight options to thousands of Americans wishing to leave Israel to Athens and destinations in the United States, as well as ground transportation options to Egypt — with supply exceeding demand on nearly every chartered flight and bus.”
