Lopez was almost killed by her Dutch husband after she sponsored him into the United States. He admitted marrying her for a green card, then attacked and terrorized her to keep her quiet. To keep her safe, the State of New Jersey put her in hiding. The Department of Homeland Security warned he was "dangerous," but refused to enforce his fraudulent immigration status despite his extensive criminal activities. Instead, the DHS illegally gave Lopez's sensitive personal information to media organizations and dumped it on the Internet.
As a whistleblower, she uncovered national security cases tied to immigration loopholes. The FBI sought them from her in late 2016; She twice presented the cases at White House meetings in 2018. Lopez first warned congressional leaders of the national security cases in 2012, but congress has repeatedly refused to close such loopholes.
Lopez testified before the U.S. Senate Judiciary Committee about her own case in 2017.
