Sen. Arlen Specter (D-Pa.) said he knows who he'd like to fill Justice John Paul Stevens' seat on the Supreme Court, but he'll tell that to President Barack ObamaBarack ObamaObama to appear on 'The Daily Show' with Trevor Noah Brian Williams slams fake news Obama: I absolutely faced racism while in office MORE on Monday.
Stevens, who turns 90 this month, said in an interview that he would "surely" retire during Obama's term.
"We have enough ex-circuit justices on the Supreme Court," Specter said, also expressing concern about any nominee getting tied up in a Senate filibuster.
Sen. Jon Kyl (R-Ariz.) said when it came to the possibility of a filibuster, "it'll all depend on what kind of person it is."
Kyl stressed that he didn't want to see "someone coming in with preconceived attitudes... we've had too much of that." The next justice should be there to simply interpret the law, he added.
"I hope he does not nominate an overly ideological person," Kyl said. "That will be the test."
