Not a coincidence but you are looking to the wrong place, All evidence so far points to the Rubio camp as the dirt tosser.
When his camp folded he had a lot of out of work people who had this info on Cruz and needing money...
The simplistic explanation is usually the right one.
Not just Rubio’s people. Don’t you think Democratic Party operatives also have this information at their disposal? It doesn’t appear that Cruz was all that discrete with his after Senate hour activities. Everybody and their mother in DC knows and has info on Ted Cruz. The question is who will spill the beans first. It appears that Cruz’s whole political career is on borrowed time now.
