The Kremlin has a response to Donald Trump's invitation to Russia to "find the 30,000 [Clinton] emails that are missing."

In essence, Russia says the U.S. needs to solve its own email problems. "The Americans needs to get to the bottom of what these emails are themselves and find out what it's all about," Kremlin spokesman Dmitry Peskov said Thursday, according to Reuters.

U.S. officials and the Clinton campaign believe Russia is responsible for the cyber breach that resulted in the release by Wikileaks of over 19,000 Democratic National Committee (DNC) emails, just before the beginning of the Democratic convention. The Kremlin emphatically denied Russia was involved.

"It is so absurd it borders on total stupidity," said Peskov, chalking up the accusations to anti-Russian sentiment.

Furthermore, the Clinton campaign also charged that Russia was trying to help Donald Trump's campaign by hacking the DNC.

A day after Trump invited Russia to find Clinton's missing emails, Trump said he was misinterpreted.

"Of course I'm being sarcastic. They don't even know, frankly, if it's Russia," he told Fox News' Brian Kilmeade. They have no idea if it's Russia, if it's China, if it's somebody else. Who knows who it is?"

Trump also rejected the idea raised by Clinton's campaign manager, Robby Mook, that his comments about the emails Thursday posed a national security concern.

"You have to be kidding. His client, his person, deleted 33,000 e-mails illegally, he said, referring to Mook and Clinton.
