Mr Kavanaugh returned to the White House for a televised appearance on Monday (local time) with Mr Trump less than a month before pivotal congressional elections.
Trump suggested that the USA public will respond to the drama that ensnared Kavanaugh's confirmation process by changing how they vote in November's elections.
Justice Kavanaugh - who vehemently denies the sexual assault allegations against - is due to take his seat in the Supreme Court on Tuesday to hear arguments about longer prison terms for repeat offenders.
"Maybe I have this wrong, but when you blocked Merrick Garland's nomination from President Obama you basically said we don't do this in a presidential election year and that we wait until the election", Wallace said.
Speaking at a White House ceremony, Kavanaugh said: "Although the Senate confirmation process tested me as it has tested others, it did not change me".
Trump continued defending Kavanaugh on Monday, saying the newly minted justice "did nothing wrong" and correctly noting that investigations found "no corroboration of any kind" from witnesses to what Ford, Swetnick and Deborah Ramirez claimed to remember from more than three decades ago. But the Christian Right didn't push for Kavanaugh's confirmation so aggressively because they think he shares the more libertarian views that retired Justice Anthony Kennedy had on abortion rights; Kavanaugh was nominated because he is an "originalist" or "strict constructionist" and a hardcore social conservative.
"Putting strict constructionists, relatively young, on the courts for lifetime appointments is the best way to have a long-term positive impact on America", McConnell said, "And today is a seminal moment in that effort".
On Monday morning, he issued a blanket dismissal of the allegations against Kavanaugh brought by Ford and two other women. "They know that the senators who are making these confirmation decisions are the people who are elected by their voters, and so as voters they have a role to play".
"I think it will be something very, very special", Trump told reporters gathered on the South Lawn. "I have been called the most vile and hateful names imaginable".
All eight Supreme Court justices attended the reception, along with the Republican members of the Senate Judiciary Committee. "That's the only thing I remember, '" Trump said at the event, impersonating Ford.
The political energy of Democrats was loudly on display in the Senate chamber as the vote got underway. In the federal lawsuit, Texas v. Ajar, Republicans from 20 different states are arguing that the ACA is unconstitutional and must be abolished in its entirety-and if that case ever reaches the U.S. Supreme Court, Justice Kavanaugh could help deprive well over 20 million Americans of health insurance.
The offending tweet read, "So whose (sic) gonna take one for the team and kill Kavanaugh?" Heidi Heitkamp, who voted "no" on Kavanaugh.
How's it looking for turnout this year, when the stakes couldn't be higher and the consequences of midterm elections couldn't be more clear?
Trump continued lashing out at Democrats when he rallied supporters in Topeka, telling them the opposition party conducted a "shameless campaign of political and personal destruction" against Kavanaugh. But I do not believe he was the assailant'.
