- McCarter's appointment remains in limbo due to Democratic senators' objections to his political views.
- Senator Menendez charged that some nominees have track records of deeply offensive public statements.
US Secretary of State Mike Pompeo is accusing a senator of blocking President Donald Trump's nominees to key diplomatic posts, including ambassador to Kenya.
Kyle McCarter, a Trump ally and director of a Christian ministry in Kenya, was named nearly seven months ago as the proposed replacement for Mr Robert Godec, who has held the US envoy post since 2012.
Mr McCarter's appointment remains in limbo due to Democratic senators' objections to his political views, including his suggestion that Hillary Clinton should be imprisoned.
Democratic members of the Senate Foreign Relations Committee grilled Mr McCarter at a July 31 hearing on his nomination.
They criticised his opposition to same-sex marriage and Obama administration refugee policies, as well as his Twitter posting on the night of Mr Trump's 2016 election victory.
“Hillary for Prison. No, really,” Mr McCarter had tweeted in regard to the defeated Democratic presidential nominee.
Mr McCarter indirectly apologised for that posting after being rebuked at the hearing by Senator Tom Kaine, Mrs Clinton's running mate in 2016.
