As a whistleblower, Lopez uncovered national security cases posed by immigration loopholes and twice presented such cases to White House staff in 2018. The FBI sought them from her in 2016. She first warned congressional leaders of the pattern in 2012. Rather than let the related loopholes expire, legislators made them permanent in 2013.
She testified before the U.S. Senate Judiciary Committee about her own case in 2017. 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 terrorized her to keep her quiet. The Department of Homeland Security warned he was "dangerous," but refused to enforce his fraudulent immigration status despite his extensive criminal activities.
Lopez currently lives in hiding with help from the State of New Jersey.
