More Americans now disapprove of Trump's approach to immigration than approve of it, a striking turnaround that followed a nationwide crackdown.

President Donald Trump called for the criminal prosecution of the Democratic candidate running for Senate in Alaska on Wednesday after revelations that her campaign appeared to be involved in recruiting a candidate with the same name as Republican incumbent Dan Sullivan.

One of them is a Republican senator and ally of the president. The other is a retired schoolteacher whom Republicans accuse of being a Democratic plant to siphon away votes.

The lawsuit centers on one of the president's longstanding complaints in the Senate race — the presence of a second candidate named Dan Sullivan who Republicans fear could siphon away votes from the incumbent in what's likely to be a photo-finish contest with Democrat Mary Peltola.

The path to a U.S. House majority runs through heavily Latino districts in states such as Arizona, Colorado and Texas, where Democrats are counting on disaffected Trump supporters to swing back their way.
