The order says the U.S. will impose “tangible and significant consequences” on those responsible for the ICC’s “transgressions.” Actions may include blocking property and assets and not allowing ICC officials, employees and relatives to enter the United States.

Human rights activists said sanctioning court officials would have a chilling effect and run counter to U.S. interests in other conflict zones where the court is investigating.

“Victims of human rights abuses around the world turn to the International Criminal Court when they have nowhere else to go, and President Trump’s executive order will make it harder for them to find justice,” said Charlie Hogle, staff attorney with American Civil Liberties Union’s National Security Project. “The order also raises serious First Amendment concerns because it puts people in the United States at risk of harsh penalties for helping the court identify and investigate atrocities committed anywhere, by anyone.”

Hogle said the order “is an attack on both accountability and free speech.”

Driving that turnaround was Sen. Lindsey Graham, R-S.C., who organized meetings in Washington, New York and Europe between Khan and GOP lawmakers who have been among the court’s fiercest critics.

Now, Graham says he feels betrayed by Khan — and is vowing to crush the court as well as the economy of any country that tries to enforce the arrest warrant against Netanyahu.
