Sen. Susan Collins (R-Maine) said in a statement Saturday that she believes the Senate should wait to vote to confirm a Supreme Court nominee to fill Justice Ruth Bader Ginsburg's seat until after the general election.

Why it matters: Collins will be a key senator in how this process plays out. As one of the most centrist Senate Republicans, whether or not the Senate confirms Trump's SCOTUS nominee could hinge on her vote.

• Collins, who is up reelection in one of the most competitive Senate races in the country, was also a deciding vote in confirming Supreme Court Justice Brett Kavanaugh in 2018, after which she faced a slew of criticisms from Maine Democrats.

What she's saying: “In order for the American people to have faith in their elected officials, we must act fairly and consistently—no matter which political part is in power."

• "President Trump has the constitutional authority to make a nomination to fill the Supreme Court vacancy, and I would have no objection to the Senate Judiciary Committee's beginning the process of reviewing his nominee's credentials."
• "Given the proximity of the presidential election, however, I do not believe that the Senate should vote on the nominee prior to the election," Collins said. "In fairness to the American people, who will either be re-electing the president or selecting a new one, the decision on a lifetime appointment to the Supreme Court should be made by the president who is elected on November 3."
