A group called "Republicans for Voting Rights" is in the process of putting up billboards in several states (e.g., Texas, Wisconsin, Pennsylvania, Florida) that read "Trump Lost. No More 'Audits'." They had an electronic one in Times Square in mid-October. It's part of a $250,000 campaign to drive home the point that Trump's a loser, and further audits will just produce the same answer: he lost.
According to the map of the billboard sites at the link, there's one in Miami, but not one the former guy is likely to see.
