WASHINGTON (AP) " Some Democratic senators weighing 2020 presidential campaigns have seized upon the opening moments of Supreme Court nominee Brett Kavanaugh's Senate confirmation hearings.

Democrats on the Senate Judiciary Committee, including Kamala (KAH'-mah-lah) Harris of California, Amy Klobuchar (KLOH'-buh-shar) of Minnesota and Cory Booker of New Jersey, demanded Republicans delay Kavanaugh's hearing Tuesday. Their calls came after a last-minute release of more than 40,000 pages of documents and the withholding of tens of thousands more.

Their show of force is aimed at countering President Donald Trump's agenda and is offering a glimpse of what's expected to be a wild, unpredictable campaign to defeat the Republican president.

Democrats warn Kavanaugh may help overturn Roe v. Wade if he's confirmed to the Supreme Court.

Trump hasn't responded to the Democrats' Tuesday opposition to Kavanaugh.
