Federal Judge Neil Gorsuch will have to be thoroughly vetted by Republican and Democratic senators.
But Indiana Republican Senator Todd Young is already pleased with the choice, one that has a direct appeal to conservatives.
"My initial reaction is that Judge Neil Gorsuch has the temperament and experience required to be a skilled jurist in the legacy of Justice Scalia," said Young.
For many Hoosiers, this issue drove their decision at the ballot box.
Congressman Jim Banks says he's very pleased the president kept his promise, by naming a pro-life judge to the highest court in the land.
"Well we know that the justice has a record on right to life issues of ruling in favor of the right to life. So that is a big plus," said Banks.
Banks adds he hopes the senate will move quickly to confirm the president's nomination.
But others want to slow down.
A statement from the president of the American Constitution Society says
"Republicans have politicized the Supreme Court, doing serious damage to our democracy."
