From the AFP, on debate at UN Security Council:

“And in highly contentious exchanges with his Russian counterpart Vietaly Churkin reminiscent of the Cold War, (US Ambassador) Khalilzad accused Moscow of seeking “regime change in Tbilisi” and of waging “a campaign of terror” in Georgia.

He said Churkin cited comments made by Russian Foreign Minister Sergei Lavrov in a confidential telephone conversation with his US counterpart Condoleezza Rice suggesting that the president of Georgia “must go“.

Russian forces are actually impeding the withdrawal of Georgian forces from South Ossetia,” (US Ambassador) Khalilzad said. “This is an unconscionable effort to continue the conflict and prevent the Georgians from taking concrete steps to de-escalate the situation.”
