Curious what you base that statement on. Are you saying the loan Cruz took out on the stock he owned was actually a campaign contribution from Goldman Sachs? Because if Cruz did get a contribution from Goldman Sachs that would be illegal because corporations can't directly donate to political candidates.
exactly. Cruz took personal loan and reported it on his tax returns. Trump has hundreds of millions of personal loans which makes him exponentially more indebted to Wall Street.
