Donald Trump appears to have deleted an unfortunate retweet about Jeb Bush's wife

In the weeks following Donald Trump's declaration that he's running for president, the billionaire mogul has taken some decidedly interesting positions on a number of issues.

Some of those positions have been highly controversial.

So much, in fact, a number of his business relationships have suffered.

The last week for Trump was so wild, he even concluded that running for president is bad for his brand. 

Trump's comments on illegal immigration have no doubt stirred much of the controversy.

Despite the outspoken entrepreneur's reputation for talking without a filter, a tweet Trump appeared to have retweeted July 4 - and then deleted - might prove that even he knows when something's gone too far.
