From an Associated Press account of a Wednesday evening White House press conference:
The news conference lasted an hour and covered topics ranging from the outbreak of swine flu — which Obama referred to as the H1N1 virus, evidently in deference to U.S. pork producers — to abortion and the recent flare-up in violence in Iraq.
Hat tip to Tom Laskawy, who first began pointing out Obama’s careful flu nomenclature on Twitter yesterday.
