Yes, but did Trump break Campaign Finance laws by failing to disclose all sources of campaign funding?
No but I am pretty sure Trump did business with the mob.
I don’t know about Trump, but Cruz didn’t. Documented proof has been posted on FR showing the loan disclosure was filed in 2012.
Better question is did Trump get any special favors from any of those politicians he brags about making donations too? http://www.merriam-webster.com/dictionary/quid%20pro%20quo
