A judge based in Colorado is reportedly considered one of President Donald Trump's top choices for the Supreme Court opening.

Of his 20 possible choices from "conservative legal circles," sources tell CNN that one of Trump's top contenders is Colorado-based judge Neil Gorsuch.

Trump reportedly said during a luncheon on Thursday, "I think in my mind I know who it is...I think you're going to be very, very excited." The decision will come after top staff weigh in on several factors, including the judge's record, age, and background.

Judge Gorsuch sits on the 10th Circuit Court of Appeals in Denver. He's reportedly become a top contender based on his views regarding religious liberty.
