LINKED TO IMMIGRATION FRAUD INVESTIGATION “For a decade, Donald Trump has relentlessly attacked Congresswoman Ilhan Omar with inflammatory rhetoric, repeatedly putting a target on her back,” the post continues. “Now, those attacks have become a useless federal raid. The congresswoman has done nothing wrong. No president should be able to use the power of the federal government to intimidate his political enemies.” In an exclusive interview with Fox News Digital last Tuesday, Vice President JD Vance said the investigation is not politically motivated. “We don’t want to be like the Biden administration. We never want to be like that, where they would allow the law to go after their political opponents,” he said.
