– President Trump said Friday that he has tested positive for the H1N1 virus and is in isolation at the White House, though his chief of staff says the president-elect is in good health. “He is in good spirits, is feeling great, and is resting very well,” said Reince Priebus in a statement, per the Washington Post. “He is not feeling 100%, but his doctors have recommended that he remain in isolation for as long as possible to avoid the spread of the virus.” The H1N1 virus is a respiratory illness that causes flu-like symptoms and is believed to be responsible for the death of at least one person in the US every year. The Post notes that Trump’s medical issues are unlikely to change the outcome of the presidential election, which is scheduled for Nov. 3. Under US law, the election is scheduled for the first Tuesday after the first Monday in November. The Democratic-controlled House of Representatives would almost certainly object to delaying the election, even if the Republican-controlled Senate voted to do so, Reuters reports. Early voting is already underway, with more than 2.2 million votes cast, according to the US Elections Project at the University of Florida. If a presidential candidate dies ahead of the election, both the Democratic National Committee and the Republican National Committee have rules that call for their members to vote on a replacement candidate. However, it is likely too late to replace a candidate in time for the election to be postponed. Unless Congress delays the election, voters would still choose between the Republican Trump and the Democratic vice president.
