I te tau 2003, ka noho a Barbour hei kawana Reipa tuarua o Mississippi mai i te wā o te Whakahou, i a ia e hinga ana i a Ronnie Musgrove. I a ia e kāwana ana, i mātakitaki ia i ngā urupare a tōna kawanatanga ki te Hurricane Katrina me te turuturu hinu o Deepwater Horizon i te tau 2010.
Ko ngā parekura taiao tino kino rawa e rua o te āhua mai i te waipuke o te awa o Mississippi i te tau 1927. I whakaarohia a Barbour hei kaitono mo te Perehitini i te tau 2012, engari i kii ia kaore ia e rere i te Paenga-whawha 2011.
