But there is still no indication which of the four finalists it will be.
Ahead of the decision, Trump has built suspense about whom his pick will be.
Earlier today, speaking from his New Jersey golf club, he also told reporters that he had narrowed the pool down to four.
"Well, it's still - let's say it's the four people. Every one. You can't go wrong".
The rollout will be modeled on the seamless presentation in January 2017 of the President's first Supreme Court nominee, Neil Gorsuch, in what was undeniably one of his most successful and most well-managed moments as President.
At stake is nothing less than a paradigm shift on the court, with the retirement of Justice Anthony Kennedy handing Trump an opportunity to place a decidedly conservative stamp on the bench.
Barrett, on the other hand, has become a favorite of religious conservatives because of her thorny confirmation hearing to the federal bench previous year.
For now, Democrats are piling pressure on Republican Sen.
All are young enough that they could serve on the nine-member high court for decades. The ad is expected to feature an introductory bio on the president's yet-to-be-named Supreme Court nominee. Mitch McConnell, R-Ky., the majority leader, has tried to warn the president through gentle nudging that Hardiman and Kethledge would be the safest choices for confirmation.
Those who discussed the president's decision, and spoke on the condition of anonymity, did not disclose the name of the president's selection. "Whoever is nominated, whoever he or she is, if they're confirmed, they're going to be there for a long time". He is 51, and among all the reported shortlisters, he is the only non-Catholic. He co-authored a book with Army veteran Mike Erwin of The Positivity Project published past year called "Lead Yourself First: Inspiring Leadership Through Solitude". Trump's sister, a retired federal judge, served with Hardiman on the 3rd Circuit and reportedly recommended him for the job. Barrett is a former clerk for Justice Antonin Scalia. He writes his own opinions, which is unlike many other judges who rely on law clerks to draft their opinions. Dianne Feinstein (D-Calif.) made Barrett a religious-rights cult hero.
Barrett has been somewhat dismissive of the notion of following Supreme Court precedents, the doctrine known as stare decisis. But he has offered little about his thinking. So, yeah, those societies who vetted the justices are extremely conservative.
"Remember, the President ran on the Supreme Court issue and that greatly enthused voters", Leonard Leo, who is now on leave from the Federalist Society, where he helped craft Trump's list of candidates, said on ABC's "This Week" Sunday.
Interested in Donald Trump? Barrett is Catholic and was better known as a professor at Notre Dame before being named a federal judge previous year.
Now key players in the appointment are reining back on the suggestion that the newly-composed court will target the pro-abortion ruling and re-criminalise the practice.
"An exceptional person will be chosen!" And she recently made it through the confirmation process, with the Senate approving her nomination to be an appeals court judge in October. Trump has been struggling with Kavanaugh's association with the Bush family, however, an issue the Post calls the "Bush factor".
"The president has to think about who is the easiest to get confirmed here", Blunt said.
Those views could have implications for independent counsel Robert Mueller's investigation of President Trump. And that is a big if.
Leading Republican US senators also toured Sunday TV studios predicting that their party would stand united over the confirmation process, and warning Democratic senators from conservative "red" states won by Trump in 2016 that if they opposed the nomination they would have to answer to voters at the midterm elections in November. I'm open to voting no. Doug Jones, D-Ala. said in a Sunday interview on CNN's State of the Union. "I don't think my role is to rubber stamp for the President, but it's also not an automatic knee-jerk no, either". If a Democratic senator votes yes, that would allow Republicans to tout Trump's nominee as bipartisan.
