Judge Brett Kavanaugh of the U.S. Court of Appeals for D.C. and Judge Thomas Hardiman of the U.S. Court of Appeals for the Third Circuit are President Donald Trump's leading Supreme Court picks, according to traders on an internet betting site.
Democrats who plan to oppose Trump's nominee are focusing on two Republican moderates, Susan Collins of ME and Lisa Murkowski of Alaska, hoping to turn them against Trump's selection.
A senior White House official says Trump called Kavanaugh on Sunday evening to inform him that he was his choice to be nominated to the Supreme Court.
The National Republican Senate Committee issued a quick criticism of Casey's announcement.
Ahead of the decision, Trump has built suspense about whom his pick will be.
