The Kentucky Republican's remarks on the Senate floor were an extended version of a message party leaders have delivered since last week.
He has now appointed Neil Gorsuch and Brett Kavanaugh which has swung the court 5-4 in the Republicans' favour, meaning abortion rights are once more in the balance.
McConnell described protesters "literally storming the steps of the Capitol and the Supreme Court", confronting Republicans at restaurants and shouting from the Senate visitors' galleries during last week's debate and vote on Kavanaugh. And he pointedly noted that these activities followed last year's shooting of GOP lawmakers at a morning baseball practice by "a politically crazed gunman".
The complaints deal with statements Kavanaugh made during his confirmation hearings.
People familiar with the matter who spoke on the condition of anonymity say the allegations had already been widely discussed in the Senate and in the public realm. Before Kavanaugh got a seat on the court, several polls were finding the opposite.
On Monday evening, Mr Trump will host another swearing-in ceremony for him at the White House.
The same question faces the #MeToo movement against sexual misconduct after the White House successfully argued that the Kavanaugh allegations should not be conflated with the rest of the movement. Roberts did not see an urgent need for them to be resolved by the judicial branch while he continued to review the incoming complaints, they said.
Nearly immediately after the Senate vote, Democrats felt the chill from faraway North Dakota.
The Democratic candidate 45 percent.
"Hoyer and Pelosi have been measuring the drapes for years now only to come away empty-handed", said Jesse Hunt, spokesman for the National Republican Congressional Committee, the House GOP's campaign arm.
"I think that's premature", Senator Christopher A. Coons, a member of the Senate judiciary committee, said on NBC's Meet the Press.
Now it's a four-week race to tell the story.
"Chief Justice John Roberts transferred both of the ethics complaints we filed with the Appeals court on Brett Kavanaugh", Democratic Coalition co-founder Scott Dworkin said in a tweet. "I think you're going to see a lot of things happen on November 6 that would not have happened before", Trump said Monday as he departed for an event in Florida.
Trump used his introduction of Kavanaugh to slam the judge's opponents.
