US President Donald Trump and First Lady Melania Trump have tested positive, the POUTS informed through his Twitter account.

Only two hours before testing positive Trump had Tweeted saying that he was in quarantine and awaiting results from a test for COVID-19 after Hope Hicks, one of his closest advisers, tested positive for the disease.

Hicks travels regularly with the president on Air Force One and, along with other senior aides, accompanied him to Cleveland for the first presidential debate with Democrat Joe Biden on Tuesday.

She was also with Trump at a campaign event in Minnesota on Wednesday and flew back to the White House with him on the Marine One helicopter after the rally.

More than 200,000 Americans have died from COVID-19 and Trump has been heavily criticised about his response to the pandemic.

Trump and his aides rarely wear masks, and nor do many of the thousands of supporters who attend his election rallies.
