@cnn: President Donald Trump on Monday urged the Supreme Court to force California to set aside potentially thousands of ballots the Justice Department claims may have been cast by noncitizens, a longshot request that multiple lower courts have rejected. The appeal puts the Supreme Court's 6-3 conservative majority in the position of weighing in on Trump's sweeping allegations of widespread noncitizen voting based on an uncertain record and an exceedingly fast timeline. Tens of millions of voters have already cast early ballots nationwide. 📸 Apu Gomes/Getty Images
