As of Monday morning, Trump was still deciding among Judges Thomas Hardiman, Brett Kavanaugh, Raymond Kethledge and Amy Coney Barrett. Cornyn told reporters that he will join about 30 Senate Republicans at the White House prime-time announcement.
Back then, Trump's decision to summon both men to Washington, and his primetime TV special reveal seemed to shock some TV news talking heads and Supreme Court scholars not familiar with reality-TV tropes. The others are Republican targets for the confirmation vote who come from Trump-won states where they face re-election this fall.
CURRENT JOB: Since 2006: Judge, U.S. Court of Appeals for the District of Columbia Circuit.
MCCAMMON: Yeah, 9 Eastern time tonight is when the White House says the news will be coming out. Any Senator who is serious about protecting the environment and fighting climate change must vote against confirmation. But the process of vetting the nominee will start right away.
Senate Majority Leader Mitch McConnell said Kavanaugh is a "superb" Supreme Court pick and that senators should "put partisanship aside" in considering him.
"No matter how intense the incoming fire, he'll stand by his legal principles", said Justin Walker, an assistant professor at the University of Louisville who clerked for Kavanaugh in 2010 and 2011.
"I do think the president has to think about who is the easiest to get confirmed here", added Sen. "I think it's a bit of a scare tactic and rank speculation", Leo said on "This Week" Sunday, saying "nobody really knows" how Trump's nominee would rule on abortion if it ever arose.
Kavanaugh, 53, is a longtime fixture of the Republican legal establishment. Meanwhile, liberal groups like NARAL Pro-Choice, Protect our Care and Demand Justice are pouring millions into ad campaigns of their own, drawing attention to what a conservative-leaning justice might mean for abortion rights, in particular.
"The president was very impressed with Barrett but said on a number of occasions it might be best to save her for a future vacancy", the source said, speaking on condition of anonymity. He launched a career that veered into Washington politics, including work on President George W. Bush's legal team for the 2000 presidential election recount in Florida.
But White House officials cautioned Sunday that Trump's informal conversations with golf partners and friends did not necessarily hint at whom he would ultimately select for the court, a decision that could tilt the bench to the right for decades.
Meanwhile, liberal groups are already calling on two moderate Republican senators - Susan Collins of ME and Lisa Murkowski of Alaska - to reject the nominee.
Kavanaugh's ties to the Bush administration and his lengthy paper trail as well as Barrett's lack of experience - just one year as a judge - were seen as negatives for each.
Justice Kennedy sometimes sided with the court's liberal justices on divisive social issues. Feinstein faced backlash and criticism, especially from Catholic leaders who accused her of being anti-Catholic. He's an evangelical Christian, has a long judicial record, no real controversy on Capitol Hill.
Trump also likes that he's written a book, reports Time, which also notes, however, that the president hasn't read it.
