"Governor Haley is a strong supporter of the State of Israel. Her presence as Ambassador will be reassuring to all those who are concerned about the increasing hostility of the United Nations toward Israel," Graham stated.
Earlier on Wednesday, Trump named Haley as his nominee for US ambassador to the UN. Her nomination will have to be confirmed by the US Senate.
Graham ran against Trump for the 2016 Republican presidential nomination. He did not support Trump as the Republican nominee after dropping out of the race in December of 2015.
