"I think so," he responded when asked on "Fox News Sunday" if it is his proudest moment.

"I think the most important thing the Senate is involved in is the personnel business. The House is not in the personnel business," McConnell said.

"The most important are the lifetime appointments to the courts, and we’ve prioritized handling President Trump’s outstanding nominations for the Supreme Court," he added.

Kavanaugh became the second Supreme Court justice confirmed under the Trump administration with McConnell as the leader of the Senate. In addition, McConnell has gotten roughly two dozen circuit judges confirmed since Trump took office.

McConnell has earned praise from more hard-line conservatives for confirming court nominees.

Even Stephen Bannon, the former White House strategist and ex-Breitbart News chief who had previously called on McConnell to resign, praised the majority leader over Kavanaugh's confirmation.

"It’s almost an out-of-body experience, I must say," McConnell joked Sunday about receiving praise from Bannon.

The bitter fight over Kavanaugh’s confirmation came after multiple women accused the judge of sexual misconduct. Kavanaugh and Christine Blasey Ford testified late last month over allegations that he sexually assaulted her during a party in the 1980s.

A supplemental FBI background investigation found no corroboration of the claims, Republicans said, while Democrats argued that the review of the allegations was too brief and failed to interview key witnesses.
