Republicans say they wish Ginsburg a swift recovery and have no inside knowledge of a retirement but are prepared to move if a vacancy presents itself.

“We’re going to fill it” if there is one, said Sen. John Barrasso (R-Wyo.), the No. 3 GOP leader. “With Justice Scalia … people might not have thought he was the one, because he wasn’t the oldest at the time. You just never know.”…

“If you thought the Kavanaugh hearing was contentious this would probably be that on steroids,” said Sen. John Cornyn (R-Texas). “Nevertheless, if the president makes a nomination then it’s our responsibility to take it up.”

While no one says they expect a Supreme Court vacancy, GOP senators also acknowledge it’s plausible that Trump could find himself with a third nominee. And one thing is clear: Most Republicans have no qualms about approving a Supreme Court pick from a president in their own party, even if it is an election year.
