Republicans are near-unanimous in demanding that President Barack Obama leave it to his successor to nominate a candidate to fill The Supreme Court seat of the late Justice Antonin Scalia.

The President insists he plans to come forward with a nominee and that there is plenty of time for the Senate to weigh in.

That sets up what could be an epic election year clash between Obama and Republicans who say they'll refuse to vote for his nominee, who could reshape the court for decades to come.

Obama hasn't said who he is considering, but Attorney General Loretta Lynch and Homeland Security Secretary Jeh Johnson are said to be on a short list on possible candidates.
