Conservative activist Laura Loomer complained on social media about children from Gaza arriving in the U.S. for medical treatment and questioned how they got visas.

The US has halted all visitor visas for people from Gaza after Laura Loomer, the far-Right activist, shared videos allegedly showing evacuees from the war-torn enclave arriving at US airports.

The admissions come amid widespread concern about a humanitarian crisis in Gaza after nearly two years of war that began when Hamas attacked Israel from the enclave. President Donald Trump has lamented the conditions and called on Israel to improve aid while also backing Israel’s plan to widen its military operation in the enclave.
