WASHINGTON (AP) — Republicans are retaining Senate seats in Tennessee, Mississippi, Maine and Oklahoma.

In Mississippi, Thad Cochran, who endured a tough primary, won re-election. And Susan Collins won a fourth Senate term from Maine.
Massachusetts Democrat Ed Markey and Democrat Cory Booker in New Jersey each won a first full term after winning special elections last year.
Earlier, Republicans picked up an additional Senate seat in West Virginia.
Tennessee voters re-elected Gov. Bill Haslam, while Republican Robert Bentley won a second term as governor of Alabama.
