U.S. Senator Bob Casey (D-PA) says he'll vote against any Supreme Court nominee President Donald Trump chooses to replace retiring Justice Anthony Kennedy.
He called the system Trump is using to pick the nominee -- mining from a pre-chosen pool of 25 conservative candidates -- "corrupt."
"It's a flawed system," Casey said. "If the President changes the system and opens it up to more people, then it's a different story."
Casey said he would have no reservations voting no on Pittsburgh judge Thomas Hardiman, one of the SCOTUS finalists, but called him a "good man."
Trump is expected to unveil his nominee Monday evening. Tune in to NPR at 9 p.m. for special coverage on Trump's SCOTUS pick.
