President Trump said he will announce his pick to fill the yearlong vacancy on the Supreme Court in a matter of days.

“I will be making my Supreme Court pick on Thursday of next week,” Trump tweeted on Wednesday.

The seat on the Supreme Court has been vacant since Antonin Scalia died last February and the GOP-controlled Senate refused to have a confirmation hearing on Barack Obama’s nominee, Merrick Garland.

Trump has reportedly narrowed his selection to three choices:

Neil Gorsuch, 49

Gorsuch is a federal judge on the US Court of Appeals for the 10th District in Denver.

A graduate of Columbia and Harvard, he was appointed to the post by President George W. Bush in 2006. The Senate confirmed him in a voice vote.

Gorsuch clerked for Supreme Court Justices Byron White and Anthony Kennedy.

His mother, Anne Gorsuch Burford, was the first female head of the Environmental Protection Agency, under President Ronald Reagan.

He has written strong opinions on religious liberty and supported corporations that have said providing contraceptives to female employees violates their religious beliefs.

Gorsuch is married with two daughters.

William H. Pryor Jr., 54

Pryor is a federal judge on the US Court of Appeals for the 11th District in Atlanta. He was nominated to the post by Bush in 2003.

Pryor, a graduate of Northeast Louisiana University and Tulane Law School, served as Jeff Sessions’ deputy when Sessions was attorney general of Alabama, and succeeded him when Sessions was elected to the US Senate.

Senate Democrats blocked Pryor’s nomination for two years, but he eventually was confirmed in a contentious 53-45 vote.

He once called the Supreme Court’s decision in Roe v. Wade “the worst abomination of constitutional law in our history.”

Pryor is married with two children.

Thomas Hardiman, 51

Hardiman is a judge on the US Court of Appeals for the Third Circuit in Philadelphia. He, too, was appointed by Bush, in 2005. His nomination was approved in the Senate 95-0.

Born in Winchester, Mass., he was the first person in his family to graduate from college.

He attended Notre Dame University and returned home after completing his studies there, driving a taxi to earn money for law school. He graduated from Georgetown University Law School.

He is considered a strong supporter of police power and gun rights and has said the right to bear arms under the Second Amendment extends outside the home.

He wrote an opinion that a jail’s policy of strip-searching inmates doesn’t violate the Fourth Amendment’s prohibition of unreasonable searches and seizures.

He lives outside Pittsburgh with his wife and three children.
