I suppose DeSantis will reveal his rationale for running during his announcement
I asked you the question, 3 times.
DeSantis is not responsible for defending Trump in his litigations with a porn actress and Playboy playmate. Further, DeSantis is not running against Trump. He is running for the GOP nomination. It so happens that Trump and now several others have entered the same contest. I will support whoever emerges as the victor, but I would much prefer a candidate who has a realistic chance at carrying the swing states, and thus the presidency.
