are planning a "Day of Action" for August 26, the anniversary of the 1920 adoption of the 19th Amendment giving women the right to vote.

Trump's other leading candidates for the post were fellow federal appellate judges Thomas Hardiman, Raymond Kethledge and Amy Coney Barrett.

On Sunday Leonard Leo, a Federalist Society official who has been advising Trump, added a fourth name: that of Thomas Hardiman, 53, a federal appeals court judge in Philadelphia.
