Here is the ad from Priorities USA which the Trump campaign wants blocked.
As for the issue of the President's use of the word 'hoax' - he did say that at a campaign rally in South Carolina at the end of February, arguing that Democrats were simply attacking him in a continuation of their efforts to impeach him.
"They tried the impeachment hoax. That was on a perfect conversation," the President said at the rally, arguing Democrats had failed.
"And this is their new hoax," Mr. Trump said.
Another Super PAC helping former Vice President Joe Biden is also out with a Coronavirus ad - which also mentions the 'hoax' statement as well.
