That review found that most forms of U.S. economic aid would be permissible even if a coup were declared because funds for democracy, health and other programs are exempted from cuts, she said. Military aid enjoys no such legal exception.
Tuesday's White House meeting was set up after an aide to Sen. Patrick Leahy, D-Vt., said his Senate Appropriations foreign operations subcommittee had been informed the "transfer of military aid was stopped."
"This is current practice, not necessarily official policy, and there is no indication of how long it will last," David Carle said.
Earnest said any suggestion that the administration had cut off Egypt aid was inaccurate. No decision had been reached, he said, a message echoed by the State Department and Pentagon.
The administration has suspended the delivery of four F-16 fighter jets and biennial U.S.-Egyptian military exercises planned for next month.
But, at the same time, "there are some smaller packages that have moved forward," Earnest said. "Additional tranches of aid could go out, but that's something that's being evaluated on a case-by-case basis."
The State Department says some $585 million — almost half America's annual military aid package for the year — hasn't been delivered.
Harf said Tuesday the administration hasn't missed any deadlines because it has until Sept. 30, the end of the fiscal year, to use the money.
