There are signs of concern in Azerbaijan that the US is in no hurry to appoint a new ambassador to that country. The candidacy of Mark Libby for the post of US Ambassador to Azerbaijan is currently awaiting a vote at the US Senate, the US Department of State announced, calling Libby a completely worthy candidate, Haqqin.az reports. The State Department is expecting for Libby's approval, and is urging the Senate to confirm him, a State Department representative said. The confirmation of Mark Libby's respective candidacy was delayed for some time at the US Senate Foreign Relations Committee. Subsequently, his candidacy was approved by the committee, but the Senate's final approval has yet to be given.
