The return to judicial matters comes after weeks of heated debate over his confirmation in the wake of an allegation from California professor Christine Blasey Ford that he sexually assaulted her when they were high schoolers in suburban Maryland decades ago. "If Kavanaugh votes like the other conservatives on the court", Hasen told me on Tuesday, "I would expect him to uphold strict voter ID laws and other laws that make it harder to register to vote".
His ascent to the court was sealed by a 50-48 Senate vote last Saturday. One of the two cases the court is hearing Wednesday involves the detention of immigrants, an issue on which Kavanaugh's vote could be key.
Kavanaugh officially took the oath in a more hurried, private procedure Saturday, but the White House version late Monday gave the Trump administration to perform the equivalent of a victory lap on live television.
During this historic Supreme Court justice swearing in-cum-Dem-smackdown, Trump said "In our country a man or a woman must always be presumed innocent unless and until proven guilty" adding, "And with that, I must state that you sir, under historic, scrutiny were proven innocent".
President Trump hailed the "momentous" occasion, and started the ceremony by apologising to Mr Kavanaugh and his family for the "campaign of personal and political destruction based on lies and destruction" that he had been subjected to. "It was a disgraceful situation brought about by people who are evil", said Trump, who also described Kavanaugh as "flawless".
Tuesday - Kavanaugh will join the bench for the first time.
The event was the third swearing-in ceremony for the nominee after a historically contentious confirmation battle following several allegations against the judge.
A special education teacher in Minnesota may soon receive some "special" attention by federal law enforcement officials after calling for the killing of Justice Brett M. Kavanaugh. Almost two-thirds, or 63%, of likely women voters said they will vote for the Democratic congressional nominee in November, compared to 33% of likely women voters who said they'll vote Republican.
The other eight justices also were at the White House Monday. The president's rendering of a verdict on the sexual assault allegations risks further antagonising political opponents at a moment that the "Me Too" movement demands accountability for sexual misconduct.
Many observers have noted that Kavanaugh's confirmation itself represent a triumph of minority rule, in two senses.
When Trump ran for the presidency in 2016, he vowed to appoint conservative judges to the Supreme Court, disclosing a list of possible candidates.
