but to go back to my point. mr president, when was the last time you had a negative test before you tested positive? and she's not the only one concerned about safety at the white house. in what amounts to a withering critique of the trump administration's handling of the coronavirus, a senior member of the president's own party had this to say. i can tell you i have not been in the white house since august the 6th, and i personally didn't feel that they were approaching protection from this illness in the same way that i thought was appropriate for the senate. following the unsavoury spectacle of the first presidential debate, the debate organisers had called for the next one, due to take place next week in florida, to be a virtual affair, given mr trump's recent diagnosis. he has dismissed that as a waste of time, and says he has no interest in taking part. the two campaigns are currently in agreement over a final debate on the 22nd of october, less than two weeks from election day, although, like everything else to do with this election, that too could change. david willis, bbc news, los angeles.
