The Senate voted 50-48 to approve Kavanaugh as protesters rallied across the country against a nominee who has been plagued by allegations of sexual misconduct as a young man and had questions raised over his candor and partisan rhetoric.
The prolonged nomination battle has roiled American politics and passions - the vote was disrupted on several occasions by angry protests from the gallery - but handed Trump one of the biggest victories of his presidency.
Flake, whose term ends in 2018, decided not to run for re-election. Citizens United allowed corporations and the wealthy to freely spend on political campaigns, creating a flow of money that helped Republican secure control of state legislatures and governors' mansions across the country, allowing them to gerrymander districts to the party's benefit and write even more restrictive voter laws.
Current members of the U.S. House of Representatives Kyrsten Sinema (D-Ariz.) and Martha McSally (R-Ariz.) are vying for his seat.
Reaction against Collins's decision to support Kavanaugh was swift.
At just 53 years old, Kavanaugh could conceivably serve on the court - now evenly divided between liberals and conservatives - for decades, tilting it to the right.
Republicans, with the exception of Sen.
Kavanaugh, a father of two, strenuously denied the allegations of Christine Blasey Ford, who says he sexually assaulted her when they were teens. They said he also seemed ready to rule for Trump if federal authorities probing his 2016 campaign's alleged connections to Russian Federation try to pursue him in court.
"Judge Kavanaugh expressed a kind of raw tribal partisanship that we don't normally hear from judges, and if he were on the court no doubt those on the left would think he decided the way he did, at least in part, because of his Republican Party leanings". Richard Blumenthal "Da Nang Dick" for his misrepresentation of his service in Vietnam on the trail in 2010, mocking him for his comments on television Friday about honesty in the Kavanaugh confirmation process.
The Senate Judiciary Committee's top Democrat, Dianne Feinstein of California, said the Kavanaugh confirmation "shifts the court far to the right, putting women's reproductive rights, civil rights, environmental protections, workers' rights, the ability to implement gun safety rules and the ability to hold presidents accountable at risk for a generation".
Alaska Sen. Lisa Murkowski, the lone Republican to oppose the nomination, said Friday she's afraid lawmakers aren't doing enough for sexual assault survivors.

The crowd has been chanting, "November is coming!" and "Vote them out!" Some believe he might try to overturn the Roe versus Wade case which gave women nationwide right to abortion in 1973.
Collins told fellow senators that Christine Blasey Ford's dramatic testimony last week describing Kavanaugh's alleged 1982 assault was "sincere, painful and compelling". Two other women later emerged with sexual misconduct allegations from the 1980s.
I also thank Judge Kavanaugh's family for remaining strong in what has been a hard time personally, they all reflect the character of true public service.
