It turns out that Mark Sanford may not have had the worst news conference of any politician in the world yesterday:

LUSAKA – A monkey urinated on Zambian President Rupiah Banda as he spoke to journalists at a news conference on Wednesday.
Banda softly shouted: “You (monkey) have urinated on my jacket,” and paused as he looked up to see the animal playing in a tree just above his chair.
“Perhaps these are blessings,” he said continuing his address amid laughter from the audience of journalists and diplomats at the State House presidential offices.
