President Trump on Thursday claimed to be the victim of "the greatest witch hunt in American history," in the wake of the Senate Judiciary Committee's report concluding that Russia sought to swing the 2016 election specifically for Trump. The investigation into whether the Trump campaign colluded with Russia's meddling began one year ago, and Trump marked the occasion by accusing Democrats of collusion instead. He also claimed that the Obama administration spied on the Trump campaign using an "embedded informant," referring to a National Review report alleging such a plot. Trump exclaimed: "If so, this is bigger than Watergate!"
