Live by the leak, and you may die by the leak.
That's the message Sen. Marco Rubio, R-Fla., is sending to his fellow Republicans, as he swears off using campaign material that originates with WikiLeaks.
"Today it is the Democrats. Tomorrow, it could be us," Rubio writes, in a statement to NBC News.
"I will not discuss any issue that has become public solely on the basis of WikiLeaks," added Rubio, who is up for re-election. "As our intelligence agencies have said, these leaks are an effort by a foreign government to interfere with our electoral process, and I will not indulge in it."
The warning from the erstwhile presidential candidate comes as Donald Trump and Hillary Clinton are preparing for their final debate Wednesday night in Las Vegas.
WikiLeaks has published a cache of emails stolen from the personal Gmail account of Clinton's campaign chairman, John Podesta. Some of the emails have proved embarrassing to the Clinton campaign, and Trump has not been shy about using this ammunition.
After Bloomberg reported on an exchange among campaign staffers discussing Clinton's reliance on a private email server while she was secretary of state, Trump took to Twitter:
WikiLeaks proves even the Clinton campaign knew Crooked mishandled classified info, but no one gets charged? RIGGED! https://t.co/FgGxDsS0a1— Donald J. Trump (@realDonaldTrump) October 17, 2016
The Clinton campaign has refused to confirm the authenticity of the emails published by WikiLeaks. The FBI is investigating the hack on Podesta's account.
The director of national intelligence and the Homeland Security secretary have blamed earlier hacks of the Democratic National Committee and other political organizations on the Russian government, calling it an attempt to influence the U.S. election.
