But as previously noted, the Trump administration has threatened to withdraw from the 47-member organization for over a year, as Haley consistently blasted the council for its "chronic bias against" USA ally Israel.
"The Human Rights Council enables abuses by absolving wrongdoers through silence and falsely condemning those that committed no offence", Pompeo said.
"We take this step because our commitment does not allow us to remain a part of a hypocritical and self-serving organisation that makes a mockery of human rights", she said.
It's not clear whether the US will quit the council in a way that means it will not cooperate with it in any form or whether it will continue to at least observe its sessions and engage in some of its investigations, the rights advocates said. "Russia, China, Cuba, and Egypt all attempted to undermine our reform efforts this past year". "If it fails to change, then we must pursue the advancement of human rights outside of the Council".
Each council session includes an agenda item on so-called country specific situations, known as Agenda Item 4, where debates on the crises in Syria, Burundi and others typically take place.
Pompeo named China, Cuba, and Venezuela as some of the worst human rights abusers who sit on the council.
The decision came as the U.S.is coming under increasing criticism from a number of worldwide human rights organizations for the Trump administration's separation of more than 2,000 children from their parents at the USA southern border.
When the Council was created in 2006, U.S. President George W. Bush's administration shunned the body. Under President Barack Obama's administration, the USA officially joined the UNHRC in 2009.
Since previous year, Haley's office has also pushed the council and its chief not to publish a United Nations database of companies operating in West Bank settlements, a so-called blacklist that Israel is concerned could drive companies away and cast a further pall over its presence in the Palestinian-claimed West Bank.
She also threatened member states, on Twitter, who voted for a non-binding resolution asking President Trump to repeal his decision to move the US embassy from Tel Aviv to Jerusalem in December.
"For years, the UNHRC has proven to be a biased, hostile, anti-Israel organization that has betrayed its mission of protecting human rights", Netanyahu said in a statement. When it was created in 2006, then-President George W. Bush decided the US would not participate.
Opposition to the decision from human rights advocates was swift.
The Trump administration's irritation with the council makeup and its agenda has been telegraphed with drumbeat regularity by Haley.
Haley criticized the HRC for its constant bias against Israel, which has been condemned by more resolutions than the entire rest of the world combined; for tolerating "not free" and "partly free" governments in the majority of its 47 seats, including some of the world's most repressive regimes; and for tackling only the "low-hanging fruit" of human rights violations instead of doing the hard work of confronting powerful abusers with HRC memberships. She repeated her ultimatum two weeks ago. During a five-year "review" to fix the Council back in 2011, the Obama administration pushed for membership reform as well.
Since 2006, the Human Rights Council has passed more than 70 resolutions critical of Israel, 10 times as often as it has criticized Iran.
