WASHINGTON Four weeks after loudly celebrating its own role in bringing home an imprisoned American aid worker from Egypt, the Trump White House has taken no steps to engage the families of three other detained Americans.

Seventeen-year-old Ahmed Hassan of Pomona, New Jersey, has been held in overcrowded Egyptian facilities with adults since December. Ahmed Etwiy, 26, and Mustafa Kassem, 52, both from New York, have each been detained for nearly four years without receiving prison sentences.

In early April, President Donald Trump personally spoke with Egyptian President Abdel-Fattah el-Sissi about the case of imprisoned American aid worker Aya Hijazi, 30, who had been jailed for almost three years. An Egyptian court acquitted her weeks later, closing a case widely seen as an unsubstantiated witch hunt devised to boost Sissis image as a tough ruler independent of Washington.

A U.S. military plane flew Hijazi home, and the Trump administration soon released photos of her in the Oval Office with the president and White House aides Ivanka Trump and Jared Kushner. Later that day, Trump boasted about the accomplishment via Twitter, in the form of a bizarre, self-congratulatory video set to the song Proud To Be An American.

The three other detainees and their families grew hopeful, Hassans pro bono lawyer and relatives of Etwiy and Kassem told HuffPost this week. But they have since been disappointed. Theres no sign that the Trump administration is treating the remaining cases as priorities, they said. And a previously unreported May 2 State Department letter to Congress about Hassans case avoided answering the question of whether Trump mentioned him or the other detainees when he met with Sissi.

My expectations changed greatly, Dr. Nagwa El Kordy, Etwiys mother, told HuffPost in an email. Seeing Aya released after all this time gave me hope that the same can happen for my son. So far nobody from the Trump administration has contacted me. And the [American] embassy in Cairo hasnt visited him for almost 3 months.

Praveen Madhiraju, an attorney for Hassan and the executive director of the nonprofit Pretrial Rights International, said the White House has not responded to multiple entreaties from Hassans family and lawyers including a letter the American teenager personally addressed to Trump.

And Mustafa Hussain Ahmed, Kassems brother-in-law, said he had no idea how to even contact Trumps team. He asked if HuffPost could connect him.

The White House did not respond to a request for comment. Will Cocks, a spokesman for the State Departments consular affairs bureau, said he could not comment on the three Americans cases because of privacy considerations.

Were aware of media reports of U.S. citizens detained in Egypt, Cocks wrote in a Friday email. One of the most important tasks of the Department of State and U.S. embassies and consulates abroad is to provide assistance to U.S. citizens who are detained abroad.

When a U.S. citizen is detained overseas, the Department works to provide all appropriate consular assistance... [which] may include attempting to ensure that the detained/arrested U.S. citizens receive a fair and speedy trial with the benefit of legal counsel; visiting detained/arrested U.S. nationals in prison to ensure that they are receiving humane treatment, including medical treatment if needed; facilitating communications with their families or others as they wish; and assisting with the transfer of funds from family and friends in the United States to pay for attorneys fees, food, and medicine while incarcerated, Cocks went on.

Representatives for the three jailed Americans say they are dealing with the challenges Cocks describes with only minimal U.S. government support.

Hassans last appeals hearing, an opportunity for him to gain an early reprieve on his one-year sentence for challenging police officers who wanted to arrest his uncle, was meant to be on April 19. But authorities pushed it to July because, they claimed, not enough police officers were available to escort the 17-year-old to the courthouse.

Etwiy and Kassem have been charged but not sentenced. Both have been in prison for nearly four years since being swept up in mass arrests during 2013 political protests. Etwiy has experienced depression and severe food poisoning, according to his mother; Kassem has had to wait up to two weeks for deliveries of the blood sugar control drug, NovoLog, that he uses to manage his diabetes, according to Ahmed, his brother-in law. Ahmed said the American consular visits were useless because officials told Kassem they could not be helpful beyond ensuring he does not die.
