WATCH: President Donald Trump announces Amy Coney Barrett as his U.S. Supreme Court pick

President Donald Trump officially announced Saturday that his pick for the U.S. Supreme Court is Judge Amy Coney Barrett.

If confirmed by the U.S. Senate, Barrett would fill the seat of late Justice Ruth Bader Ginsburg, and would ideologically swing the court in favor of conservatives.

Charles Lipson, professor emeritus of political science at the University of Chicago, told KCBS Radio that this nominee will replace the most important feminist jurist in the history of our country with a conservative.

"This'll be very different from before," Lipson said. "It really moves from a 5-4 to a 6-3. Sometimes, there were 5-4 liberal decisions, with Chief Justice Roberts voting with other liberals."

Senate Republicans, led by Majority Leader Mitch McConnell, are readying for confirmation hearings in roughly two weeks, with a vote in the full chamber expected before the election on Nov. 3.

“The American people are going to take a look at this nominee and conclude, as we are likely to conclude, that she well deserves to be confirmed to the U.S. Supreme Court," McConnell told Fox News.

The Senate needs a simple majority to confirm a Supreme Court nominee.
