President Donald Trump named Judge Neil Gorsuch as his U.S. Supreme Court nominee.
Gorsuch, 49, has served for over a decade as a federal judge on the U.S. Court of Appeals for the 10th Circuit.
He graduated from Harvard Law School and Oxford University before serving as a clerk for two Supreme Court justices. Gorsuch has also worked at the Department of Justice.
The Democratic National Committee issued a statement on Gorsuch, saying his nomination "raises some very serious question" about whether he "can approach each case with an open mind to make fair decisions based on the merits."
"Gorsuch spent his career representing big corporate clients against the interests of ordinary Americans and consistently ruling against workers in favor of big businesses," the DNC's statement said.
Shortly after the announcement, the White House released a statement saying Trump was "transparent, principled and consistent" in choosing a Supreme Court nominee.
The release noted that Trump provided an initial list of 11 possible candidates for the job in May 2016. In September, he added 10 more names to the list and Gorsuch was among the candidates on the final list.
President Donald Trump is expected to announce his U.S. Supreme Court nominee Tuesday night.
His nominee, if confirmed would replace the late Justice Antonin Scalia, filling a seat that's been vacant for nearly a year.
Trump is expected to, as promised, pick a nominee with the same judicial philosophy as Scalia, in that he or she will strictly interpret the Constitution as it was written.
Judge Neil Gorsuch, of the 10th Circuit, and Judge Thomas Hardiman, of the 3rd Circuit, top Trump's short list of potential nominees, sources with knowledge of the decision told ABC News.
During a meeting with small business owners Monday, Trump said he chose a "person who is unbelievably highly respected."
White House press secretary Sean Spicer confirmed Monday that the nominee was on the list the president already released.
The announcement is expected Tuesday at 8 p.m. EST.
