On Thursday, October 22, Donald Trump deleted a tweet he
retweeted that suggests that genetically modified corn crops were
creating "issues in the brain" for Iowa voters. Tagging Donald Trump's
official account, a twitter user @mygreenhippo tweeted: "Ben Carson is
now leading in the poll in Iowa...Too much Monsato in the corn creates
brain issues?" which was retweeted by Trump's account but now he's
blaming a young intern for the RT.
