US Ambassador to the United Nations Susan Rice arrived in Tripoli, Libya, today in a surprise trip, just a month after she voted to end the UN’s mandate of the NATO mission that ousted Moammar Gadhafi.

“It is good to be in Libya,” she tweeted shortly after arriving.  ”I’ve come to witness progress & lend support to Libyan & #UN personnel.”

Rice eight months ago played a pivotal role in convincing the UN Security Council to authorize the mission to protect civilians.

In a statement, Rice’s office said she had met with the country’s interim leaders, including Transitional National Council Chairman Mustafa Abdel Jalil and new Prime Minister Abdel-Rahim al-Keeb.

Rice visited a warehouse that was converted into a prison and torture room, calling it “an atrocity committed by the Qadhafi regime as it was collapsing.”

“The stench of death & cruelty was pervasive,” she tweeted.

While there Rice met with former prisoners and families of the missing and dead.
