Cory Booker

Booker’s decision leaves 12 Democratic candidates and two non-white candidates in what was once the party’s most diverse primary field.

Ten Democratic candidates met Thursday night for a nearly three-hour debate. It was the first featured a newly narrowed down field, and the first featuring former Vice President Joe Biden and Sen. Elizabeth Warren on the same stage.

Sen. Cory Booker was the first Democrat on the Senate Judiciary Committee to release documents that had been designated as "confidential" as the third day of the Kavanaugh hearings began.
