US President-elect Donald Trump has filed a lawsuit against the Des Moines Register and its pollster, accusing them of 'brazen election interference' for publishing a poll that showed Democrat Kamala Harris with a surprising lead of three percentage points in Iowa just before the election. The lawsuit alleges that the poll misled the public, energized Democrats unnecessarily, and forced Republicans to waste resources in areas where they were already dominant. The Register's parent company dismissed the lawsuit as meritless and affirmed its commitment to defending its First Amendment rights.
