The Democratic candidate for president of the United States, Hillary Clinton, unexpectedly cancelled a meeting with potential donors in North Carolina on Tuesday and was reported to have cancelled a meeting with voters in California as well. Her campaign headquarters announced that the pneumonia that she suffered last week had apparently returned. In a Twitter post, Republican presidential candidate Donald Trump said "Hillary Clinton is taking the day off again, she needs the rest. Sleep well Hillary – see you at the debate!" In another tweet, he pointed out that Clinton was helped up several steps onto the stage by Tonight Show host Jimmy Fallon when she appeared on the program.
