WASHINGTON — Loretta Lynch's long wait to become US attorney general ended Thursday, with the Senate voting to confirm the veteran New York prosecutor five months after President Obama submitted her nomination to Congress.
The 56-43 vote was highly anticipated for numerous reasons: Lynch's status as the first African American woman to be nominated for the post, the high-profile role the Justice Department has played in national concerns over race and policing, the political implications for senators facing voters next year, and the unusual delay — the longest for an attorney general nominee in 31 years.
In the end, the margin was wider than had been expected: 10 Republicans, including majority leader Mitch McConnell of Kentucky, joined the Senate's 44 Democrats and two independents in supporting Lynch. Forty-three senators, all Republicans, were opposed.
Lynch is expected to be sworn in as the nation's 83d attorney general on Monday, according to Justice Department officials not authorized to comment publicly.
Obama said in a statement that ''America will be better off'' with Lynch in charge of the Justice Department. ''She will bring to bear her experience as a tough, independent, and well respected prosecutor on key, bipartisan priorities like criminal justice reform,'' he said.
Outgoing Attorney General Eric Holder, stepping down after more than six years, said Lynch would be ''an outstanding attorney general, a dedicated guardian of the Constitution, and a devoted champion of all those whom the law protects and empowers.''
Getting the Senate to a final vote had been a slow and rancorous affair, with Obama deeming the spectacle ''embarrassing'' last week. It gave Democrats frequent opportunities to lambaste McConnell over a span of months and right up until Thursday.
''I guess I was naive in thinking my Republican colleagues would treat Loretta Lynch with the dignity that she and her office deserve,'' minority leader Harry Reid, a Democrat from Nevada, said on the Senate floor. ''Perhaps my mistake was forgetting that for Republicans, this isn't about Loretta Lynch. It's about President Obama.''
Obama nominated Lynch, 55, to replace Holder in November. The Senate, then under Democratic control, did not act on the nomination, preferring to spend precious time in the lame-duck session on judicial appointments that party leaders believed would stall in a Republican-controlled Senate.
A Republican Senate, the thinking went, would not dawdle in confirming a replacement for Holder, a frequent target of Republican enmity. That proved not to be the case, especially after Lynch became entangled in a deep partisan rift over Obama's immigration policy.
During questioning before the Senate Judiciary Committee in late January, Lynch said she believed Obama's executive actions on immigration last year passed legal and constitutional muster, angering Republicans who considered them an overreach.
''Ms. Lynch has said flat-out that she supports those policies and is committed to defending them in court,'' Senator Jeff Sessions, a Republican from Alabama, said Thursday. ''So I think Congress has a real role here. We do not have to confirm someone to the highest law enforcement position in America if that someone is publicly committed to denigrating Congress.''
Senator Ted Cruz, a Republican from Texas, said that, under Lynch, ''We are sadly going to see more and more lawlessness, more recklessness, more abuse of power, more executive lawlessness.''
After the January hearing, it took nearly a month for the panel to advance Lynch's nomination, and once it did, the nomination became caught up in an unrelated political dispute.
An otherwise noncontroversial bill to combat sex trafficking became stuck on the Senate floor after abortion-rights Democrats objected to provisions that would extend existing federal restrictions on abortion funding to a new victims' compensation fund. At that point, McConnell tried to force Democrats to accept the language by tying Lynch's nomination to the anti-trafficking bill's passage.
The move incensed Democrats, some of whom spoke in racial terms about what they saw as shabby treatment of a pioneering black woman. Minority whip Richard Durbin, a Democrat from Illinois, for instance, said Republicans had asked Lynch ''to sit in the back of the bus,'' a reference to civil-rights icon Rosa Parks.
On Thursday, Senator Claire McCaskill, a Democrat from Missouri, called the Republican opposition ''disgusting'' and ''base politics at its ugliest.''
''It doesn't matter if you're qualified,'' she said. ''That makes no difference. We have a new test: You must disagree with the president who nominates you. . . . This defies common sense.''
Obama did not blame Lynch's race for the delay, but he showed increasing exasperation as the delay mounted.
