President Donald Trump and Senate Majority Leader Mitch McConnell, both Republicans, have said they expect the Senate to vote on a Supreme Court nominee well before the elections.
The president said that the five possible nominees included two women.
His retirement, which takes effect on 31 July, gives Mr Trump a second Supreme Court appointment in his 17 months in office after he selected Neil Gorsuch previous year, who has already become one of the most conservative justices.
During the candidate vetting the last time, the White House asked all the contenders whom they would pick instead of themselves - and they all said Gorsuch, said the person, who was not authorized to disclose private conversations.
"I think it's going to be the early cutoff dates for abortion that you're gonna be seeing going up to the court that could challenge Roe v. Wade, because Roe v. Wade and its cases that have followed have made clear that before the time of fetal viability it's for the woman and her doctor to make the decision", Northup said.
"We have great people. highly talented, brilliant, mostly conservative judges", Trump told reporters aboard Air Force One en route to New Jersey.
A key Democratic senator is encouraging President Donald Trump not to pick a Supreme Court nominee who's openly interested in overturning Roe v. Wade.
Among them: Leonard Leo, who is on leave from the Federalist Society; John Malcolm of the Heritage Foundation; and attorney Don McGahn, now the White House counsel. Barrett clerked for Antonin Scalia, the deceased Supreme Court justice.
"I may have two of them come up, like the old days, to Bedminster", Trump said, referring to the staff and Cabinet interviews he held there in late 2016 during the presidential transition. Republicans have a narrow, 51-seat majority, and all eyes will be on a handful of Republicans who have been supportive of abortion rights, and on red-state Democrats facing re-election in November.
"All we are doing is following the long-standing tradition of not fulfilling a nomination in the middle of a presidential year", he said in a March 2016 interview with Fox News Sunday. She points to what's known as a "heartbeat bill" in Iowa, where state lawmakers recently approved one of the strictest abortion laws in the nation.
Northup, of the Center for Reproductive Rights, said restrictive laws recently passed by several states could work their way to the Supreme Court.
In Arkansas, a legal battle is now playing out over a law that imposes limitations on access to medication-induced abortions.
MS and Louisiana recently passed legislation banning abortion after 15 weeks with limited exceptions. "You know, usually they don't say that".
Unlike Heitkamp, Donnelly and Manchin are Democrats who generally oppose abortion rights and are endorsed by Democrats for Life, the "pro-life voice of the Democratic Party".
Schumer said it would be "the absolute height of hypocrisy" for the Senate to move forward with confirming Trump's pick during an election year after using the 2016 election as the rationale for refusing to act on Garland.
A key part of the vetting process will likely be reviewing the judge's history of written opinions, said a person with knowledge of Trump's thinking, who noted that the range of Gorsuch's past opinions impressed Trump. "I'm looking for someone who doesn't wear their own politics on their sleeve, being a jurist".
