Exclusive: Rubio Won't Talk About WikiLeaks, and Neither Should Donald Trump

Rubio's stand puts him directly at odds with Donald Trump and other Republican.

"WikiLeaks has provided things that are unbelievable," he said at a rally in Colorado on Tuesday, accusing the media of ignoring the leaks. "The media, you have to remember, is an extension of the Hillary Clinton campaign. It's an extension. And without that, she would be nowhere."

While Trump regularly slams the news media for not paying enough attention to the stolen emails, Rubio argues that making an issue out of the WikiLeaks disclosures plays into the hands of the Russian government.

"I will not discuss any issue that has become public solely on the basis of WikiLeaks," Rubio tells ABC news.

Earlier this month, the United States government publicly accused Russia for a series of hacks and email leaks that targeted U.S. political institutions — intrusions that top officials said were authorized at the highest levels of the Russian government.

For his part, Trump not only talked about the hacked emails in the first two debates but also raised questions about about whether Russia was really behind the hacking.
