U.S. officials had raised Hijazi's case with Egypt soon after Trump took office on Jan 20, aides said.

President Trump shakes hands with Aya Hijazi, an Egyptian-American aid worker at the White House Friday in Washington, D.C.

In 2014, Egyptian authorities charged them with sexual abuse and trafficking of those children, a claim that human rights groups had long argued was unsubstantiated and false.

Hijazi became an internationally recognized symbol of Egypt's growing oppression. Powell had been in the region traveling with U.S. Defense Secretary James Mattis. Her Egyptian husband and four coworkers were arrested as well. The State Department has said they are living up to the terms of the deal.

"... I left Cairo very confident, very confident in the avenues we have to advance our military-to-military relationship, which has been a bedrock and has stood solid all these years".

After that meeting came a break in the Hijazi case, and most analysts see a direct link between the two.

The Egyptian president spoke with Mattis at the Pentagon during his visit to Washington D.C.in early April, which was aimed at increasing US military support to Egypt, according to Egyptian media.

During a visit to Washington early this month by Sissi, Spicer said that the issue of Hijazi's imprisonment was raised by "the team".

"I just want to let everybody know in case there was any doubt that we are very much behind President Sisi", Trump said. Sissi's post-coup crackdown has been particularly severe against civil society groups, especially those receiving money from overseas. The meeting also helped fix ties to Egypt which had become strained under the Obama administration.

While President Barack Obama was uneasy with the elected government of Mohamed Morsi, whose political organization was tied to the Muslim Brotherhood, his administration rejected Sissi's charges of terrorism ties.

Egypt is the second largest recipient of US military aid after Israel, benefiting from a package worth $1.3 billion while an additional $150 million is intended for developing the Egyptian economy.

Why it matters: This could give biotech executives a chance to make a direct pitch for the value of federal medical research funding, something they've wanted to do ever since President Trump's budget proposed a almost 20 percent cut in NIH funding.

Nunes' decision to call off the original hearing with Yates, Brennan and Clapper came only days after the committee's first public hearing in which Comey confirmed that the bureau was investigating President Trump's associates' ties to Russian Federation. "Her vindication is proof that even small efforts to improve our world can create ripples that shake even the most entrenched authoritarian governments".
