'Russia, Find Hillary's 33K Emails': Here's a Recap of Trump's News Conference

Krauthammer: Trump's Email 'Trap' Catches Hillary in 'Complete Contradiction'

Democratic Texas Rep. Joaquin Castro slammed Donald Trump for "inviting" Russian hackers to locate Hillary Clinton's deleted emails, and suggested the hacking of Democratic National Committee emails was a "digital Watergate."

Trump said during a news conference today: "Russia, if you’re listening, I hope you’re able to find the 30,000 emails that are missing.”

A Trump campaign spokesman attempted to clarify the comment, saying that Trump "did not call on, or invite, Russia or anyone else to hack Hillary Clinton’s emails today."

The Clinton campaign has accused Trump of encouraging Russian espionage against the United States and meddling in domestic politics.

Castro added to that, saying that he does not think Trump was joking, as his campaign claimed.

"It's incredibly irresponsible in this digital age, the technological age that we're in, to be inviting a foreign government to interfere with the political process."

Castro added that he believed the hacking of the DNC was potentially a "digital Watergate."

He said he would like to know who is behind the hacking of the DNC and if any American or campaign received information that was hacked.
